it is very difficult--long winded and expensive to " import" a "foreign" spouse into the UK.
i'm in the process--and we are now 4 years in to the 5 years settlement route, which will have cost me about 10,000 pounds overall. there are conditions to meet--including a minimum income or other financial means. like many other Brits--i knew nothing of all this when we first met and started a relationship.
