CHECK YOUR STAMPS
Recently we’ve seen a few posts about people getting incorrect stamps in their passport - either on entry or by an immigration office when getting an extension.
Immigration officers are human and therefore can make mistakes. The onus is on you to check the stamp they gave you.
One recent one was a person with a UK passport that was stamped in with a ผผ.90 stamp effectively showing they could stay for 90 days when they should have received a ผ.30 visa exempt stamp for 30 days. Probably was on the same flight as a group of Russians that correctly got the ผผ.90 stamp and the immigration officer just didn’t notice the error.
The immigration computer system almost certainly has the correct date you are allowed to stay until but the manual stamp shown in your passport may be wrong.
The fact that the entry stamp (or extension stamp) is incorrect does not mean you have the ability to stay until that date.
Another common error is that people with a PDF Visa from the evisa system are stamped for an exempt entry for 30 days as the officer hasn’t noticed they have a visa, so they don’t get the correct 60 day stamp. Almost certainly in this case the computer system will show they can only stay 30 days, when it should be 60.
Again the onus is on you to check. As a general rule you can get an airport stamp corrected at most immigration offices (some may say you have to go back to the airport to correct it), but if a land entry stamp then 100% you’ll need to go back to that entry point to get it corrected. If the error is from an extension stamp from an immigration office then almost certainly you’ll need to return there to get it corrected - although that may differ from office to office.
