For tourist visa, how many days before the expiration date should I apply for a visa extension?
For example, if my visa will expire on 15th April, and I go for visa extension on 5th April, will the Immigration office count the extension from 6th April onwards or will the extension be applied after the expiration date (16th April)?
Appreciate your recommendations.
TLDR : Answer Summary
You can apply for a tourist visa extension up to 30 days before your current visa expiration date. When you apply for the extension, the additional time will be added to the end of your current entry stamp, meaning that you do not lose any days by applying early.
