Thank you both for your replies. You've been very helpful.
I have a few more tricky questions, which might not be tricky at all.
The 3 years that I need to be resident, is that 3 years from when I got my fiancé visa, or from when I got my spouse visa, or from when I entered the UK as a tourist first?
I entered as a tourist first for 9 months to be with my fiancé at the time. Then left to apply for a fiancé visa to come back. Then we got married and I was issued a spouse visa.
So in essence, when does the 3 year period apply from?
Also, do I have to be IN the UK to apply for citizenship? Lets say we move to France, can I apply from there? Or do I need to be resident in the UK for the entire time of processing?
Lastly, do I need to send in my foreign passport to apply for UK citizenship? Or can I still travel during this period? We have a business and travel quite a lot, so will need to plan accordingly if I need to send in my foreign passport.
Thanks again, and apologies for all the questions.
