She is here on a work visa but single entry

Can are-entry permit be obtained in Bangkok so she can enjoy a shopping day out with us at Mae Sai

Iseem to re-call going to a one stop place near Chatuchak with fotos (A?) and 1000 baht ?

Any tips welcome

If 90 day entry can likely obtain anywhere but if extension of stay the re-entry should be from office providing that extension. Would need to go to Chiang Watanna if in Bangkok. The one stop moved from Central Latphao area several years ago and do not believe they would provide unless have extension from them.

Thanks as ever for speedy response

no need for re entry permit,if your going over the bridge (border)at mai sai,use the vip pass 2 photo stats front page passport 100 bht easy,see chiang rai forum for more info,done it twice myself now,and im on extension of stay visa.
