hi,

I have Non-B Visa Extension valid till 31 March 2016 on my Old Passport.

I went back to my country to get new passport.

yesterday I returned to Thailand. Immigration officer at Suvarnabhumi Airport put stamp on my new passport ( Non B Visa , Valid Till : 31 march 2016).

I am confused here.

Do I need to go my local Immigration ( hatyai) for Visa stamp transfer or not?

Visas are never transferred.

You should ask immigration to transfer relevant information including detail of the extension to the new passport.

I assume you mean that you have a non 'B' visa valid until Mar 31st. Not an extension of stay.

• The visa will stay in the old passport. It's not transferred to the new passport.
• You need to show both passports until the visa in the old passport has expired.
