I have non-imm retirement extension expiring on 13 November. Returning to Thailand on 7 November. The plan is on 9 November to submit visa extension application in Jomtinen. 

 

Will only having 7 days remaining on extension cause any problems at BKK immigration? What departure stamp will I get, etc?

 

Thanks for advise.

No problem to do your extension with only 7 days remaining on your current one. You could do it on the last day if you wanted to.

You will get stamped into the country to the 13th using your re-entry permit on entry.
