If I have a green card for 2 years, can I divorce before this times expire without loosing it?

I assume that you are a conditional resident through your wife and then you will have to file an I-751 application to remove the conditional basis on resident status within the 90 day period before the second anniversary of the conditional resident grant. If you are divorced or have a legal separation, you are prohibited from filing a joint petition with your wife to remove the conditional basis. However, with a divorce, you can file a petition by yourself on the basis that the marriage was bona fide at the beginning and attach all evidence showing such in the I-751 petition. You can also remove the condition by showing that you are a battered spouse or that you would suffer extreme hardship if you return to the home country, such hardship having occurred during the period of conditional residence.
