What about working using SSN while in OPT. Will there be any problem while filing H1 as I am with dhoti consultancy.

As long as there is some relation to the place where you are working and your study, there will be no problem. Like if you have done MBA and working on Gas Station on OPT then you can say I was managing that Place. So you will not be in Problem. But if you have finished your degree on CS and working on Gas Station then you cannot have some direct relation. So in that case, it might be a problem.

while filing H1 will there be problem of working at two place

The work should be related to the course. Otherwise, it may have a problems.

Thanks.

There is no working hour limit in OPT. You can have multiple jobs.For 1 yr OPT,I do not think it will be a problem. To work in an extended OPT,your employment should be related to your area of study anyway. otherwise you don't get ur new EAD card..

sooner or later all students will become illegal with a policy and economy like this... k garnay guru haru...
