What should I do if my name on my visa application doesn't match my passport?

I think your application will be cancelled. Names must exactly match the passport.

After you upload your biodata photo triple check and correct if necessary the information propagated by the OCR as it's prone to misread.

No need to call, they will cancel your application directly and you can apply again. And of course you will have to pay the application fee again. And yes, it happened to others also, many are not able to write their names correctly, so don’t worry, you are not the only one

Yes this happens a lot. Thai embassy is strict about name. What you write on DTV application must match your passport exactly. If your passport shows full middle name and you only wrote initial, it can cause problem at airport or with airline. Better to fix it now before you fly.

You should contact the NY consulate fast by email and phone. Send them your passport page and your application number and explain you wrote initial instead of full middle name. Some consulates can correct it or tell you to apply again. Do not wait until you travel because immigration in Thailand also checks name exactly as in passport.

To avoid this kind of small mistake that can cost a visa, I like the checklist in Unlock Thailand by Isla Rey on Amazon, it reminds you to copy passport name letter by letter. It is a handy guide to double check before you submit.

Errors in the passport information can not be corrected of you nor the Embassy, and will lead to rejection and loss of the 10.000 baht visafee, as it is told explicitly on most embbassy websites.

It MUST matched EXACTLY what you have in the passport. Unfortunately, it is very likely your application will be cancelled automatically and no refund will be issued :-(. One needs to triple check and then triple check again.

Has to match your passport MRZ zone exactly. Kiss your application and processing fee goodbye.

Application will be cancelled by the Consulate.!
