Overview

Can You Stay Longer in Vietnam?

Vietnam is one of Southeast Asia's most captivating destinations, and it is no surprise that many visitors want to stay longer in Vietnam beyond their initial visa allowance. Whether you are a digital nomad working from a Saigon cafe, a retiree enjoying the low cost of living, or a traveler who simply fell in love with the country, extending your stay is a common need.

However, Vietnam's immigration rules for tourists are relatively strict. Standard tourist e-visas are single-entry only and cannot be extended while you are inside the country. The practical solution used by thousands of long-term visitors is the visa run — exiting Vietnam and re-entering with a fresh visa. This guide covers every method for staying in Vietnam past your initial visa, including costs, risks, and step-by-step instructions.

Bottom line: If you are on a tourist e-visa, you cannot extend it from inside Vietnam. A visa run via the Moc Bai border to Cambodia is the fastest, cheapest, and most reliable way to reset your stay and remain in the country.

Visa types

30-Day vs 90-Day Vietnam E-Visa

Understanding the two main e-visa options is the first step to planning how long you can stay.

Feature 30-Day E-Visa 90-Day E-Visa
Max stay 30 consecutive days 90 consecutive days
Entry type Single entry Single entry
Government fee (via our service) 1.4M VND 2.4M VND
Processing time (urgent) ~4 hours ~4 hours
Can be extended in-country? No No
Best for Short trips, budget travelers Long stays, fewer visa runs

30-Day Vietnam E-Visa

The 30-day Vietnam e-visa has been the standard tourist visa option for years. It allows a single entry and a maximum stay of 30 consecutive days. The government fee is approximately $25 USD (about 600,000 VND) when applied directly, or 1.4M VND when processed through a visa run service that handles the application for you. This visa is a good choice if you are visiting for a few weeks, but it means you will need to do a visa run roughly once a month if you want to stay longer.

90-Day Vietnam E-Visa

The 90-day Vietnam e-visa was introduced to reduce the administrative burden on both travelers and immigration authorities. It is also single-entry, but it grants a stay of up to 90 consecutive days. The government fee is about $50 USD (approximately 1.2M VND) when applied independently, or 2.4M VND via a service. For anyone who wants to stay longer in Vietnam without frequent border crossings, the 90-day visa is significantly more convenient — you only need to do a visa run every three months instead of every month.

Recommendation: If you plan to be in Vietnam for more than 30 days, apply for the 90-day e-visa. The extra cost is modest compared to the time and money saved on additional visa runs.

The practical solution

How a Visa Run Lets You Stay Longer

A visa run is the process of exiting Vietnam, having a new e-visa processed while you are outside the country, and re-entering with a fresh visa stamp. Since Vietnam e-visas are single-entry and cannot be extended in-country, this is the only practical way for most tourists to reset their allowed stay without leaving Asia entirely.

Why You Cannot Extend a Tourist E-Visa

Under current Vietnamese immigration law, tourist e-visas (both 30-day and 90-day) are strictly single-entry and non-extendable. There is no immigration office in Vietnam that will process an extension for these visa types. The only exception is for certain visa categories such as the 5-year visa exemption certificate (for overseas Vietnamese or spouses of Vietnamese citizens), which can be extended in-country through an agent. For the vast majority of tourists, exiting the country is the only option.

The Moc Bai Visa Run — How It Works

The Moc Bai border crossing in Tay Ninh province is the most popular land border for visa runs from Ho Chi Minh City. Located about 80 kilometers northwest of Saigon, it connects directly to Bavet, Cambodia. Here is how a typical Moc Bai visa run unfolds:

  1. Early morning pickup. You are picked up from your location in HCMC, typically between 4:00 AM and 5:30 AM. Shared vans or private cars depart early to beat traffic and reach the border before queues build up.
  2. Drive to Moc Bai. The drive takes approximately 2 hours via National Highway QL22. Your driver handles the navigation while you rest or prepare your documents.
  3. Exit Vietnam. At the border, you proceed to Vietnamese immigration, present your passport and current visa, and receive your exit stamp. This takes about 5 to 10 minutes.
  4. Send exit stamp photo. You take a clear photo of the new exit stamp and send it via WhatsApp to your visa run coordinator. This triggers the urgent processing of your new Vietnam e-visa.
  5. Cross into Cambodia. You walk the short distance through no-man's-land to Cambodian immigration. Apply for a Cambodia visa on arrival — fee is approximately $43 USD (1.1M VND), payable in cash. Processing takes 10 to 20 minutes.
  6. Wait in Cambodia. While your new Vietnam e-visa is being processed (roughly 3 to 5 hours for urgent), you can wait in the Bavet area. Most services coordinate the timing so you return just as the visa is approved.
  7. Re-enter Vietnam. Once your new e-visa is ready, you cross back through Vietnamese immigration, present the new visa, and receive your entry stamp. Welcome back to Vietnam with a fresh allowance of 30 or 90 days.
  8. Return to Saigon. Your driver takes you back to your HCMC accommodation. You are typically home by early to mid-afternoon.

Total time: 6 to 8 hours from door to door. Total cost: approximately 2.4M to 3.5M VND including transport, Cambodia visa, and the new Vietnam e-visa fee. Private car options cost more but offer earlier departures and greater flexibility.

Cost analysis

Cost Comparison: Options for Staying Longer

Here is a full breakdown of what each option costs, including visa fees, transport, and associated expenses.

Option Cost per cycle Frequency needed
30-day e-visa + visa run ~2.4M VND
(transport 800K + Cambodia visa 1.1M + new e-visa 500K partial) Every 30 days
90-day e-visa + visa run ~3.5M VND
(transport 800K + Cambodia visa 1.1M + new 90-day e-visa 2.4M) Every 90 days
Multiple-entry business visa ~$200–$400 USD
(agent fees + processing) 3–12 months
5-year visa exemption ~$50–$100 USD
(if eligible) Up to 5 years
Overstay + fine ~500K–1M VND per day
+ risk of ban or deportation ⚠ Not recommended

Which Option Is Cheapest Long-Term?

If you plan to stay longer in Vietnam for 3 to 6 months, the cheapest repeated option is the 90-day e-visa with a visa run every 3 months. Over a 12-month period, this costs roughly 14M VND (about $570 USD) including four visa runs. By comparison, using the 30-day visa would require 12 visa runs in the same period, costing roughly 29M VND — more than double.

If you qualify for a multiple-entry business visa or the 5-year visa exemption, those options become significantly cheaper per day. However, most travelers do not qualify for these and rely on the e-visa + visa run combination.

Pro tip: If you are staying longer than 6 months consecutively in Vietnam, consider alternating between visa runs and short trips to other Southeast Asian countries (Thailand, Laos, Malaysia). This reduces the appearance of continuous residence and may help you avoid scrutiny at immigration.

Practical details

Warning

Overstay Risks: What Happens If You Stay Too Long

Overstaying your Vietnam visa is illegal and can have serious consequences. While Vietnam's enforcement has become stricter in recent years, many travelers are still caught off guard by the penalties. Here is what you need to know before considering an overstay.

Overstay Fines

Vietnam immigration imposes escalating fines for overstaying your visa:

  • 1 to 10 days overstay: 500,000 VND (~$20 USD) per day
  • 11 to 30 days overstay: 1,000,000 VND (~$40 USD) per day
  • More than 30 days: 1,500,000 VND (~$60 USD) per day or more, plus possible legal action

These fines are paid when you finally exit Vietnam. Immigration officers will not allow you to leave until the fine is settled in cash. The fine is calculated based on the exact number of days overstayed, including partial days.

Serious consequences of overstaying: In addition to fines, overstaying by more than 10 days can result in a temporary or permanent ban from re-entering Vietnam. Overstays of 30 days or more may lead to detention, deportation at your own expense, and a blacklisting that prevents future visa applications. Multiple overstays, even short ones, can flag your passport in the immigration system for increased scrutiny.

Can You Pay the Fine and Stay?

Some travelers assume they can simply pay the overstay fine and continue staying indefinitely. This is false. The fine is only applied at the point of exit — you cannot pre-pay it to "extend" your stay. Once your visa expires, you are unlawfully present in Vietnam. If you are caught by immigration police in a random check (common at airports, train stations, and police roadblocks), you face immediate detention and deportation procedures, not just a fine.

What If Your Flight Is Delayed?

If your departure flight is delayed or canceled and you overstay as a direct result, keep documentation from the airline. In most cases, immigration officers will waive the fine if you can prove the overstay was caused by circumstances beyond your control. Carry a copy of your flight itinerary and any airline communications.

The safest approach: Plan your visa run or departure at least 3 to 5 days before your visa expires. This gives you a buffer in case of unexpected delays at the border, traffic jams, or processing issues. Never cut it down to the last day.

Alternatives

Other Ways to Extend Your Vietnam Stay

For most tourists, the e-visa + visa run combination is the most practical and cost-effective way to stay longer in Vietnam. However, there are a few alternative routes worth knowing about.

Multiple-Entry Business Visa (DN / DT)

If you have a business connection in Vietnam, you may qualify for a multiple-entry business visa valid for 3, 6, or 12 months. These visas are typically arranged through a Vietnamese company or an immigration agent and require an invitation letter from a sponsoring organization. The cost ranges from $200 to $400 USD including agent fees. A business visa allows multiple entries and exits, so you can travel freely without doing visa runs.

Vietnam Temporary Residence Card (TRC)

The Temporary Residence Card is the gold standard for long-term stays. It is available to foreign investors, highly skilled workers, and those with a valid work permit. A TRC can be valid for 1 to 10 years and allows multiple entries. This is not an option for most tourists but is worth knowing about if your circumstances change while in Vietnam.

5-Year Visa Exemption Certificate

Overseas Vietnamese (Viet Kieu) and foreign spouses of Vietnamese citizens can apply for a 5-year visa exemption certificate. This allows entry without a visa for stays of up to 180 days per entry, and it can be extended in-country. This certificate is processed through Vietnamese embassies and consulates abroad.

Fly to a Nearby Country

Instead of a land border run to Cambodia, some travelers prefer to fly to a nearby country (Thailand, Malaysia, Singapore, or Laos) and apply for a new Vietnam e-visa while abroad. This takes longer (often 1 to 3 days including flights and accommodation) and costs more, but it doubles as a mini-vacation. Budget flights from Saigon to Bangkok or Kuala Lumpur can be as cheap as $50 to $80 round trip.

Frequently asked questions

Visa Extension & Visa Run FAQs

Can I extend my Vietnam visa without leaving the country?

For most tourists on e-visas, no. Vietnam e-visas (30-day and 90-day) are single-entry and cannot be extended while you are inside Vietnam. You must exit and re-enter with a new visa. Some visa types like the 5-year visa exemption certificate can be extended in-country through an immigration agent.

What is the difference between a 30-day and 90-day e-visa?

The 30-day e-visa allows a single entry and a stay of up to 30 days (fee: 1.4M VND via our service). The 90-day e-visa also allows a single entry but permits a stay of up to 90 days (fee: 2.4M VND). Both are non-extendable in-country.

How does a visa run help me stay longer in Vietnam?

A visa run resets your allowed stay. You exit Vietnam (typically via Moc Bai to Cambodia), a new e-visa is processed while you are outside the country, and you re-enter with a fresh visa stamp valid for another 30 or 90 days. This process can be repeated indefinitely.

What happens if I overstay my Vietnam visa?

Overstaying incurs fines of approximately 500,000 VND per day for the first 10 days, and 1,000,000 VND per day after that. Overstays of more than 10 days risk temporary or permanent re-entry bans. Serious overstays can lead to detention and deportation at your own expense.

How often can I do visa runs to stay in Vietnam?

There is no official limit, but immigration may scrutinize travelers who enter Vietnam too frequently. Most long-term travelers do visa runs every 30 or 90 days without issues. If you plan to stay for many months, consider applying for a longer-term visa to avoid questions at the border.

How much does a visa run cost from Saigon?

A full visa run from Saigon via Moc Bai costs approximately 2.4M to 3.5M VND total, including shared transport (~800K), the new Vietnam e-visa fee (1.4M for 30-day or 2.4M for 90-day), and the Cambodia visa on arrival fee (~1.1M VND / $43 USD).

Can I do a visa run on a weekend?

Yes, the Moc Bai border is open 7 days a week from 6:00 AM to 10:00 PM. However, weekday runs are recommended because e-visa processing is faster on working days. Weekend runs may have longer processing times.

Do I need a Cambodia visa for a Moc Bai visa run?

Yes, you need to enter Cambodia to complete the exit process. A Cambodia visa on arrival is available at the border for most nationalities. The fee is approximately $43 USD (1.1M VND), payable in cash with one passport photo.
