Thailand eVisa for US Travelers: When You Need It, Official Site & Timing
Short answer: When a visa is required, file it on the official Thai e-Visa site before you travel; a short US vacation under 30 days is usually exemption instead. Stand: 25 September 2026.

When you need an eVisa
This guide is for US travelers who actually need a visa for Thailand—not for every trip.
If the purpose is vacation and you will stay less than 30 days, a US passport holder does not need a visa. That path is called visa exemption. For that case, use the Thailand visa exemption guide instead of starting an eVisa file.
You need an eVisa when your stay, purpose, or passport path falls outside that short vacation exemption—for example, a longer visit, work-related travel, or another purpose that Thai rules treat as visa-required. In those cases, the application belongs online before departure, not at the airport as a last-minute substitute for planning.
For the broader Thailand entry map, see the Thailand hub.
Official apply channel
Needed visas are filed through the official Ministry of Foreign Affairs e-Visa website at https://www.thaievisa.go.th/. If you want help with a supported electronic request, my-evisas.com can assist.
Applicants no longer mail documents to the embassy for this process, and the embassy does not accept walk-in or drop-off visa filing at the moment. Every visa can be requested through that e-Visa channel except the Thailand Elite visa, which follows its own path.
Timing and confirmation
Build in real buffer. The embassy highly recommends applying around one month before your intended travel date. Because of volume, e-Visa processing may take longer than usual, so plan to apply at least 30 days before departure and not more than 90 days in advance—most visas are typically valid for only 90 days from the date of issuance.
Picture a US traveler with a mid-November departure who waits until late October. That shorter gap can still miss the mark when the queue is longer than usual. Treat one month as the practical target and keep the 30-to-90-day band in view. If the embassy asks for more documents, the status is usually updated within 3 to 5 business days after you upload them.
After approval, a confirmation email is sent. Print a copy to present to the airline and Thai immigration when you travel.
Apply from outside Thailand
File while you are still outside Thailand. The Royal Thai Embassy cannot issue a visa to a foreign national who is already in the country. If you are already on Thai soil, this channel will not create a new visa for you from the embassy side—complete the eVisa step before you leave home.
Fees
The visa application fee depends on the type of visa you request, and the fee is non-refundable. Confirm the amount on the live official fee page when you submit; do not assume an old quote will still match.
TDAC is still required
An approved eVisa does not replace the Thailand Digital Arrival Card. All non-Thai nationals entering by air, land, or sea must complete the TDAC online within 3 days before arrival. That form is an immigration requirement, not a visa. Details: Thailand TDAC.
FAQ
Can I apply for a Thailand visa by mail?
No. Visa applications go through the e-Visa channel. Applicants are no longer required to mail documents to the embassy, and walk-in or drop-off filing is not accepted at the moment. Thailand Elite remains the named exception outside that portal path.
How soon before travel should I apply?
Aim for about one month before travel. Apply at least 30 days before departure and not more than 90 days ahead. Because of volume, processing may take longer than usual.
What if I am already in Thailand?
The embassy cannot issue a visa for a foreign national who is currently in Thailand. Apply from outside the country before you travel.
Does an approved eVisa replace TDAC?
No. You still complete the TDAC within 3 days before arrival. See the TDAC guide.
