A question about my one-year Non-Immigrant B, Multi-Entry Visa.. . I want to be clear about whether I need to get a re-entry permit or not, and that Immigration at the airport in CM will stamp me in for another full 90 days when I return from a 4-day trip to Malaysia. After my first 90 days in country, I did a trip to Mae Sai, did a land crossing and got my next 90-day stamp (which expires in about a week's time). I needed no extra documents - it was easy like old times. Is there anything that will be different crossing back by air from KL that I should prepare for?
