The Department of Homeland Security (DHS) proposes to amend F-1 nonimmigrant student visa regulations on optional practical training (OPT) for certain students with degrees in science, technology, engineering, or mathematics (STEM) from U.S. institutions of higher education. Specifically, the proposal would allow such F-1 STEM students who have elected to pursue 12 months of OPT in the United States to extend the OPT period by 24 months (STEM OPT extension). This 24-month extension would effectively replace the 17-month STEM OPT extension currently available to certain STEM students.
Status, authorized period of stay and unlawful presence are three VERY important concepts in US immigration laws with far reaching implications. The nuances in these concepts are so intricate that they can trip up even my fellow-lawyers. I see issues in this all the time.
Here is a brief primier to enable you to understand the basics. This is by no means an exhaustive analysis.
Status
I-131 and I-765
With the exception of the I-765s for OPT for which there is a few weeks lag time all other I-131s and I-765s are being worked by the NSC as soon as they arrive at the center.
Screening of cases
1. I have been on H-4 for almost 3 yrs now, and starting my MS in Spring 09 (on H4 status itself). But now I want to change to F-1 for personal reasons. I have the following doubts. request your clarification:
If I want to get my F-1 stamped from India, do I need to submit I-539 form also to the ISO of my school ?
2. How long should I be on F-1 before when I will be eligible to apply for OPT and work using the same?
3. If I want to start working as a grad assistant from Fall 09 semester, do I have enough time to apply for a change of Status through USCIS, CA ? Will I get an approved F-1 by then ?
1. No. An I-539 is used if you want to change status within USA.
2. You need to check with your school about CPT. The requirements for OPT as I recall are two full semesters on F-1.
3. No one can predict that. Sorry.
