Something struck me last night.
We are off to the USA next week.
My wife has 2 passports, Thai in Thai name, UK with my surname.
To get the travel approval my wife must have her tickets in the name of her UK Passport so the airline can see that she is approved to travel to the USA without a visa.
That means her boarding pass will have her UK name.
When she leaves through Thai immigration her boarding pass will not match the name on the passport. Now that has happened before, eg leaving Dubai recently when her boarding pass had her Thai name and the passport she showed had her UK name.
Never done it going out of Thailand before..... gonna be an issue at all?
