I was born in the UK spent most of my life in NZ and hold a UK passport as well as NZ.

Am thinking of a trip in the future to UK and europe with the Thai Gf of 4 years.

Wondering how she would get on travelling in different countries. France Germany etc.

Is there an EU visitor visa or would we have to apply for seperate visas for each country we wanted to visit?

Your girlfriend will need a visa for the UK and one Schengen Visa which will cover her for France, Germany and most other countries in Europe.

I personally would advise her to get the UK visa first, and then apply for her Schengen Visa, which should really be for the first country in the Schengen Area you want to visit.

Have a read through the threads and come back with any specific questions, but basically she needs to prove that the trip is affordable, either by her or you, and that she would return home at the end of the trip.

Good luck
