Has anyone applied for a tourist 60 day extension (15+45) at one office (receive 15 days, then visa under consideration) and then tried to get the next 45 day stamp in another city/ office? Or is it required to return to the same office and city?
TLDR : Answer Summary
If you have applied for a 60-day tourist extension and received a 'under consideration' stamp in your passport, it is mandatory to return to the same immigration office to finalize the next 45-day extension stamp. Other offices, even within the same province, cannot process your extension due to the existing 'under consideration' status.
