I have a British passport. My wife is Japanese and has an indefinite leave to remain (she is currently awaiting her British passport) - she has lived in UK for 15 years or more. I also have a daughter with British passport.
We've stayed in Portugal for around 70 days. We're heading back to UK for 2 weeks and then will come back to Portugal for another 90 days.
I'm wondering is there likely to be any problem on re-entry to Portugal? I'm guessing there won't be (because I'm allowed up to 6 months before needing to register here and my wife (I'm hoping) assumes the same conditions as me (since we are married).
