I am a student with a 5 years F1 visa. I married an US-citizen, I want to know if the marriage invalidates the visa.
Marriage to a U.S. citizen does not in itself invalidate your F-1 visa.
Can I file a Green Card Application while I am still a student?
Yes, however, it may be unlikely that you will receive your Permanent Residency before your OPT expires. This could be a problem if you plan on continuing in school or extending your F status. Indicating you are in intending immigrant renders you ineligible for extensions of your F student visa. There may be additional complications and we highly recommend you discuss this matter with one of our Attorneys.
Can I change to dependent F-2 status while my wife is in F status and applying for OPT?
Optional Practical Training (OPT) is accorded to individuals in F-1 status. You should be able to file a COS application to be accorded F-2 status.
I am in the process of applying for OPT. Can I leave the country and return in F status?
You will be unable to return in F status if you leave the country. Also, once you depart you are ineligible to use the remainder of the OPT period.
Do I respond to a Request for Evidence?
Since you have already filed an application for change of status it is important that you respond to the Request for Evidence from the USCIS. Not doing so could affect an application for a visa at the U.S. Consulate.
Misc Student Visa Questions
My friend's son wants to come to U.S. for higher studies or employment. He will be completing his BE Btech. What steps he needs to take -
1. For coming to U.S. to do his M.S. in Computer Science.
-- He must immediately obtain admission to an M.S. program from an accredited U.S. University. This University would have to provide him with an I-20 Admissions Record that he would then have to use to obtain a visa.
2. Come here for employment, securing a job and H1-B Visa.
-- For this, he would have to find employment with a U.S. employer capable of employing him in a specialty occupation (one that requires the minimum of a bachelor's degree).
Can an F-1student enroll for less than full-time classes?
The answer to this question is not simple. The student may be permitted by the Designated School Official to enroll for less than full-time where it is recommended for academic reasons or due to the student's illness [I guess a complicated pregnancy qualifies]. The regulations are not specific as to how long a student may take less than a full-time load. An F-1 student is considered to be in status during the school's annual vacation, if the student is eligible for and intends to resume full-time studies in the next term.
