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.
It was great help from Rajiv Sir to advice free to F1 students issues and questions. My friend recommended me to contact Rajiv Khanna Law Firm. God bless you with everything you wish. I applied my OPT and got rejected because of applied ahead of time. Then I again applied and got it. Now I have completed my program but still not have degree. I was worrying about my next status without having US degree in hand. But Mr. Rajiv suggested and explained it in real good manner and now I am just going with that flow. Thank you Mr. Khanna for your service to community in USA.
