Got a visa on arrival. AFAIK it’s for 15 days which you can see with “TR-15,” but I was stamped for 30 days. I’m going to assume the 30 days is incorrect and it’s 15 days. This means I have to leave before the 18th right?
TLDR : Answer Summary
The user received a visa on arrival, believed to be valid for 15 days, but was unexpectedly stamped for 30 days and is unsure if they must leave before the 18th. Comments clarify that the correct duration is indeed 15 days, starting from the day of entry, and suggest correcting any stamp errors at an immigration office.
