Does anyone out there have first hand knowledge of the maximun time period for any Thai Visa ??? i e for the US is is not unusual to have a visa term of 10 Years.

One year is about it for non immigrant visa for general issue. There are probably longer types for official/diplomatic type use but you can search for that yourself.

Maximum utilize time for a normal Thai visa is 12 months (Multiple netry Non-Immigrant visa). Maximumim stay is 90 days entry.

The NON-OA (Retirement pre-approved visa) is valid for one year and Don Muang normally gives you one year on arrival).

The NON-BA (Business pre-approved), I don't know the exact details.

There is also a 3 year APEC visa, and there is a Thailand Elite Card with a validity of 5 years. Both the APEC and Elite visa holders are given a 90 days entry into the Kingdom each entry.

I think the NON-BA [pre approved business] in the visa someone mentioned to me..... where can I search out the details of this type of visa ? I was told that it is good for 3 years. By check out I mean in English of course

many thanks

"Ash here, you will get a correct answer Thai Immigration"

Thank you kind person, I have already done as you suggested and have received 6 correct answers.... so i thankkk youuussse verry musccch

I am trying to determine if the NON - BA is one that is only available in your home country, or if it would be obtainable in a nearby country. In two local [nearby country Embassys they indicated that they did not issue any visas for longer than one year.... I thought that perhaps this was one of the situations that may only be available with BOI status

Again serious thanks
