You do not have to inform USCIS immediately. You can do it anytime before or after the two year period. Understand the when I say "notify" I mean file an I-751 waiver application
If you get divorced, now you can file I-751 by yourself, you do it within the time provided by law.

I agree with Alena. Though I cannot emphasize enough how important it is to timely file the I-751. It was extremely serious consequences, especially in case of divorce.

Don't wait! It is best to file as soon as possible, while you have witnesses who remember you and your spouse. If the divorce is final, start working with a competent and experienced immigration attorney, now. It can make a big difference in preserving the evidence that proves that you had a good faith marriage. Good luck.
