Got my non-immigrant F visa yesterday. It is good for 90 days after which I will get a new one for a year

The handling agent didn't tell me about reentry permits ;-(

I have three questions:

--Can I get the reentry permit at Suwwanaphum (and Don Muang?)? Pretty straight forward or do I have to deal with queues?

--If I get the annual multiple entry permit for 3,800 baht will I need a new one when the 90 day visa is extended, or will the annual multiple entry remain valid?

--If I want to get the reentry permit from Chaeng Wattana, do I have to go in person or can an agent do this? Any suggestions? I like in Asoke area

Thank you

Yes, both Swampy and Don Mueang have re-entry desks, the one at Suvarnabhumi is open 06-00 to midnight, Don Mueang appears to be 24 hours. Never seen a queue at Swampy not been to Don mueang recently.

The re-entry permit is only valid for your current stay, so every time you get an extension you need a new one.

The form states apply in person, our office lady seems to get ours without our presence but she knows the staff at CW.

At the airport you can only get a re-entry permit after you have check-in with the airline, you can't get them in advance there.
