I'm currently studying in US as a graduate student under F1 visa. My visa got expired on May 2012, but I have received new I-20 from my university, thus maintaining my student status.
My uncle applied for immigration visa for my father, and I'm derivative beneficiary of the case. Although, I'm 26 now, with Child protection act my adjusted age is below 21, and as I talked with NVC over phone, they said I would be able to immigrate with my parents if every thing goes well. Our PD is July 2001; and looks like we can face the visa interview within next 4 months.
Now, I have grad-assistant-ship here in my university, which means when I go to my country to face the interview I need to take vacation from my university, (which can't be greater than 1 month). Only if, when I go to my country, and we get the immigrant visa right away, I will be fine. In all the other cases, for example delay due to administrative processing; or denial of the immigrant visa, particularly I will be in trouble.
To be on safe side, should I just apply for a new F1 visa right away after I get to my country? And is it doable? (I did get My F1 visa, after our F4 petition was approved, AOS was submitted, and we were working on DS 230 form)
I would appreciate your response, and suggestion regarding what I should consider doing.
