@Caitlin *****
as you are now late to report 90 days as it was due June 12...and is now June 21...you had a 7 day grace period past June 12th...
I think you can wait until you return to close out the Under Consideration stamp on July 14th in your passport ...as the fine remains the same at 2,000 Thai baht.. It does not increase if late reporting.
