I am married to us citizen and filed I 485 I 130 and other forms in april. My question is if i get divorced right now how long it takes and what happens to forms i filed.

And if i get married to another us citizen can I apply again these forms?

Thanks

Why do you want to get divorced? It seems soon to marry another US citizen. But, to answer your question the I-485 is based on your current marriage. If you get divorce, you will need a waiver.
