Arrived at Bangkok airport immigration on March 29. Noticed the immigration officer stamped the wrong date (April 27) for my TR Visa. I went to another immigration officer at a desk behind the primary immigration officers and explained the issue. Attached is a photo of the incorrect stamp that she corrected. I thought she would give me a completely new stamp versus crossing out the date with a pen. Is this standard procedure in these types of situations? I want to be sure this won't cause issues when I apply for an extension in a couple months.
