I will be going out of Thailand right before my work permit expires and I intend to return to Thailand after the permit has expired. I will for Non O apply for dependent visa extension after I arrive ( have all documents and meet all the requirements). Intend to get visa on arrival at the airport

My questions are:

1. What is the best visa or visa options when I return to Thailand

2. do i need a return ticket to get visa at the airport?

3. any other requirements to get the visa at the airport

I appreciate in advance

Moved to Visa section.

You will probably get a 30 day visa exempt entry when you arrive not a visa on arrival. A visa on arrival costs 1000 baht and is only for 15 days for those from certain countries.

If you are getting a visa exempt entry you will need nothing when you enter the country other than you passport and arrival card.

It would best to get a single entry non-o visa before returning.

What is the basis for your dependent extension. There are many that can fall under that description.
