*No*. Some of the people who had responded to this said that proof
of application for status change (to F1) is sufficient to start working
part-time at school. However, the ISO advisor at my school and
Mr. Rajiv Khanna (a helpful lawyer on net who can be reached at
rskhanna@immigration.com) said that while you are on H4, work is not
permissible. You have to have your F1 to begin work at school.
Q: I am already on H1 from X company and have an offer to work for Y
company on parttime basis.
My question is can I still obtain H1B
for that company. And would it have any effect on My green card
processing which has not yet begun.
You may do a part time H-1. For GC, there is no affect.
Q: I've seen people who have two H1 visas due to a change in job - now, my
friend has a problem - she is in India and has a H1 visa for
company A.
She however has not been able to come here due to personal problems. If
she were to seek a job from some other company B in the US, is it
required that she must have used her H1 for A before B can process a H1
for her?
There is no such requirement. She can go forward with co. B.
Q: I am currently on H1B for the past three years. Next year I plan to
go to school full-time and hence will have my H1B converted to F1
student visa).
It will probably take me a year and a half to get my
degree. This means that I will have been on an H1B for 4 years and
then on a F1 for 1.5 years. My question is, can I get another H1B
after I come out of school? What will be the duration of that H1B?
Since the maximum duration of a H1B is 6 years, will my earlier 4 years
be counted, so that I might get a new H1B for 2 years? Or will I get
a fresh H1B, unrelated to the the one I have currently?
You will get an H-1B for two years.
