Cheers.. we're moving tomorrow evening. So it'll have to wait until monday. The thai agent i used said change it at the next extension (nov) which i think is quite wrong.
Dear Tod, yes, my non B is an extension, 1st issued Aug 2015, last year was a renewal.
Finances are not an issue, and as I said we will marry in Sept, and then I plan to apply for the marriage visa, it would just be easier if I didn't have to do a visa run.
