Before your wife can obtain US citizenship, she will need to obtain her permanent residency ie., green card. If you are a permanent resident and you just recently filed your I-130 for your wife, from the Philippines, it could take up to 3 years for her to complete this process. At such time she can join you in the US. After five years, she can then apply for US citizenship. If you can obtain US citizenship yourself, you may be able to reduce the times considerably.
