Dear British blonde,

There is no problems at all in your case, first of all they will never ask you for any kind of your documents in the airport excepr your passport and the visa.

As for working permis you will also wont face any problem cause usually they never ask for your birth certificate or even for your degree certificate, it only could be needed for the personnel department in the company you will work for but not in any official government office.

It is not complicated here as you imagine.

Best wishes,

Ayman
