Citizenship-confused

[littlebush]

Can anyone direct me to a website that spells out the requirements of citizenship please?
I've been on the uk border agency and just cant find anywhere that actusally explains how to qualify.

for info, im a uk citizen, wife is russian, we got married 2 months ago, just want to know how soon she can get a passport in simple terms.

thanks

Check spouse citizenship.
In short, after 2 years on spouse visa, apply for ILR. After three year in the UK and meeting the requirements, apply for citizenship. After a citizenship is granted (several months on average), apply for passport.
