I have a multiple-entry O-A visa. I'll be leaving Thailand several times over the next few months.

Where do I apply for a re-entry permit? (My current residence is in Kalasin).

Can I get the re-entry permit in Bangkok, if so, where?

Or do I have to go to Sakon Nakon?

How much is the re-entry permit.

Moved to Thai visas etc.

Unless your original visa has/will expire you do not want re-entry permits with a multi entry O-A visa as using the visa entry you get a new one year from date of entry each time - a re-entry permit would only keep your exit permission to stay time alive.

The cost is 1k single or 3.8k multi entry.

Why would you want a re-entry permit if you have a valid multi-entry visa. Does your multi-entry "O-A" visa expire during your proposed travels? In that case you do need a re-entry permit.

I will probably get banned but have you ever looked into what visa or extension you are on??????????

Thanks for all your replies.

I arrived in January with my initial O-A visa, and won't have to do a 90-day report until mid-April.

I'll be traveling to Laos in April and then to Singapore and Khmer in May. I didn't know if I had to get a re-entry permit in conjunction with the multiple entry O-A visa.

Do I need to bring proof of income to with me?

Thanks

If you have a valid multiple O-A visa you don't need a re-entry permit, as long as you return to Thailand before the date the visa from the embassy expires.

No need for proof of income when you enter Thailand.
