I'm English and I'm taking my Thai step-son for a trip to France with me soon. I was planning a further trip to the UK but the French consulate have taken so long(two and a bit weeks) to issue an EEA family member Schengen visa that I'm worried I will not have time to get the UK EEA family permit before we leave in 10 days. I could apply in France, when I arrive but will only have just over 2 weeks then to sort it out and will have to use post or take 400km each way trip.

I know the UK will issue a second passport if you need to travel while your passport is being processed - does the same apply for Thais ?

My Thai wife has three passports. Thai, UK and NZ!

My kids have two, USA and Thai each. A friends wife has a USA and Thai too. Just wish I had a Thai passport.

I think the OP is talking asking if the step son can have two Thai passports. The answer I am pretty sure is 'no'.

Dual nationality of course, is fine.
