Yes, if you come from Africa or some Asian countries, you might be asked , I was travelling by Ethiopian Airlines, and they have a list at the gate. What countries are you coming from. They stopped a lot of African there and put them in a separate line and also some Asian. However, later on, they let them go, but after a deep verification.
thank you for detailed reply, actually it would be my first time, I am currently married to a Thai, and will be travelling with my wife as well, just planning to stay 60 days more.
