No, only during government working hours. So, if you learn on a Friday afternoon that you have to leave the country the next day for urgent reasons, you are out of luck.
Speaking of which, I have to report to immigration now, as my "Permanent Residency" is anything but permanent - I have to get new stamps every year, as I leave the country on business on average twice a month. I always used to make my yearly pilgrimage to CW in the morning and am out of there before lunch. Pretty fast for a government office, if the travelling within Bangkok wouldn't take hours. It would be even better if this yearly reporting could be done online, like the 90-day report for the non-imms.
Anyway, this time I can only be there by 1pm. Does anybody know whether I can still get the Non-Quota Immigrant Visa (not "Re-entry Permit") and the Endorsement within the same day if I only arrive in the afternoon? Thanks.
