Once the conditions on your wife's resident status is removed, she should be able to file her Form N-400 Application for naturalization, usually within few months of her receipt of her 10 year green card. As a general rule of thumb, your wife's eligibility for citizenship is 3 years, counting from the date she got her temporary green card. So, if she has been a green card holder (even on a conditional basis) plus the time spent in processing her permanent green card for a total of 3 years, she can file for citizenship. Please note that in addition to the 3 year lawful residence requirement, there are a number of other requirements for naturalization. You should speak to an immigration attorney to discuss all of these requirement before proceeding to file her Form N-400 citizenship application.
