Immigration Site

Hi everyone,

I did a research almost through the website and I have to say that you guys are very nice and it is a very good website. Because my situation is a little bit different so I am very appreciate if you guys can help me out of it.

Here is my situation:

I am Vietnamese, I am F1 visa holder with opt status. My opt will expire on Jan 2011 and I am eligible to apply for 17 month extension.
My future wife is US citizen, she came to the US 8 years ago through marriage. She got divorce with her husband 1 weeks ago after sponsoring her parents to immigrate to the US (they arrived here 1 month ago).
We plan to get marriage as soon as possible and she will sponsor me to have GC.

Here is my question:

1) Is it difficult for me to get GC because she just divorced and sponsored her parents?
2) Should I wait until my 17 month OPT extension valid to apply for GC? (so USCIS wont consider me to pursue GC because my status is going to expired).

PS: my priority is to apply for GC as soon as possible because we consider to purchase a house together. I really do not want to wait until next year to apply for green card and start looking for a house again.

I am looking forward to hearing from your advise. Thank you very much in advance and I am very sorry for my bad English.

1) when did she become a USC and when did she divorce?

More importantly, when did she get her own GC? Having gotten her own GC through marriage, she has to wait 5 years after her GC approval before she can sponsor a new spouse.

PS: my priority is to apply for GC as soon as possible because we consider to purchase a house together. Why the rush to buy a house? House prices arent going to shoot up anytime soon.

1) when did she become a USC and when did she divorce? She became USC on May 2009 and divorced on Sept. 2010.
