Seems unusual then, but they can do whatever they want really. Maybe they're trying to get you to do a retirement extension instead if you're over 50.

You said it yourself. You're going to "arrival immigration" which means you'll be entering Thailand and need an arrival card.

It sounds like you applied for the 90-day non-O visa based on marriage, and they came to visit you after that. And now you've applied for the 1-year extension (not a visa, it's an extension), and so they are coming to visit you based on this brand new application. Each extension is a brand new application, you are not renewing anything, you are applying for a brand new extension.

TDAC is irrelevant. But many airlines require it

@Samantha *******

you'll need to check with your airline. Immigration in Thailand almost never asks.

If you both have Italian passports then you don't need a visa. You'll be eligible for visa exempt which will give you a 60 day stamp when you enter. About a month into your trip you'll need to go to the immigration office where you are and apply for the 30-day tourism extension.

You don't need to do anything. You've already entered. The TDAC is no longer relevant.

Non immigrant visas do not require proof of onward travel out of Thailand.

If the visa application asks for travel dates, just put your intended entry date and an exit date within 90 days since it's a 90 day visa. They know this type of visa has a path to staying in Thailand long term, so it's just a paperwork routine to get it issued.

as I said, you clearly don't understand the way Thailand works. Including something that's not requested is just asking for trouble. You'll confused them and likely complicated things for yourself.

Thais are taught from elementary school not to ask questions, not to question what they are told. They are given a list of things to check, and anything that deviates from that list is a problem. They have no capacity to think outside the box, to help you if something doesn't match exactly what's on their list. They are punished for making suggestions to their manager that could improve something, because then the manager looks bad.

When you have an official government process, you provide what is asked for. Nothing more, nothing less.

@Jason *****

the Thai government is not a UK employer. They do not care what agreement you have with some company. They want a criminal history certificate.

But as I said, I don't know why you're even asking about this because you likely won't need it.
