Do I Complete Immigration in Bangkok or Samui When Flying Through Bangkok to Samui?

And as Seoirse Grant has many replies and advice. .I will close commenting for tonight.

Good Luck to the OP.

Okay, I just hear you where only 6 months in Thailand during 2019, that you are now 5 months away from Thailand.

Get a letter from the company that they are going to hire you, but they need some more copies bla bla bla and that is why you now come in using the Tourist Visa and will go for an Non Immigrant B visa and work permit. Do not worry to much.

I flew to Samui last September from Houston, to Tapei, Bangkok, then Samui. Did my immigration paperwork in Bangkok.

I can not tell what the Immigration officer decide, my advice, get the documents, apply for the Non Immigrant B visa and then make your way to Thailand.

To avoid the hassle you had last year after living inside Thailand using Visa Exempt Entry and Tourist Visa, you did take care this time.

What long time visa are you going to present to Immigration?

Considering your history and issues before, I dont rate your chances wherever you enter.

If your bags are booked through to Samui you do immigration in Bangkok when transferring

Checking straight through all depends on airlines code sharing

I think you would be best asking the airline about it. Do you think you may get rejected at BKK?

I recently flew to Krabi via Bangkok from the UK. It was one booking, my bag went straight onto Krabi, but I cleared immigration in BKK.

Depends on your ticket.

I'm assuming that things are the same as the last time I through checked (5 years ago).

If it's one ticket booked through, then the bags will also be checked through and you should clear at Samui.

If they're separate tickets, or the onward airline doesn't have an interline agreement, then you'll pick up your bags and do immigration in Bkk- then recheck your bags.
