您好，请教您问题。我和我老公几年前已经I－－１４０批了，我是副申请。他已经拿到绿卡。我因在加拿大，所以没一起递交４８５。我们现在准备给我办理，该如何办？我要等多久？
-Two choices:
1. you enter US using B2 or other visa, then file I-485. If you are Canadian citizen, you don't need a visa and just use the passport to enter US, then file I-485 about several months later. Of course, you need to check whether your spouse's PD is still current. If no, have to wait for the PD to be current to file I-485.
2. Your spouse file I-824 for you, then you can apply for the immigration visa in Canada to enter US to become a green card holder. But this way may take more time (about one year to two years).
