Thank you for your advice JAJ.
That allows you to decide whether to go for the EEA Family Permit (as John suggests) or to instead apply for a spouse visa under standard UK rules. Lots of people go for the EEA permit without realising that it's a lot longer to permanent residence - 5 years rather than 2.
Unfortunately we cannot really afford a lawyer right now... And since my EEA Family Permit expires in a few weeks, I thought it's easier for us to apply for Residence Permit/Document. Also, 5 years you mentioned will give us more time to think about our future (whether or not we stay in this country and so forth).
Does your husband want to apply for British citizenship? (which EEA state is he from?). It may shorten your time to get British citizenship if he does do so.
And do you plan to have UK-born children in future?
My husband is from (Republic of) Ireland and neither he or I want to apply for British citizenship in the future. As for children, we are not sure about that yet but yes maybe...
So I am afraid there are so many uncertainties at the moment, but one thing for sure is that I want to remain in the UK with my husband.
Any further advice/information would be much appreciated.
