My son is a US citizen and he is 2 yrs old. we have OCI card (Overseas Citizen of India) for him and it is valid until March 2020. He has been staying in India for the past 1 yr with his grandparents.
My question is How much duration can he live outside the US? Does US citizen have any limit for living outside the USA?

I have my H-1 extension till 2020. I recently visited India and got visa stamped 2020 as well but while coming back as my passport validity was till Feb 2018 - I got the I94 till Feb 2018. How do I extend my I-94?

1. Working with Employer A - but the place of employment is the end client B (on site work at Client B location). PERM and I-140 approved. At this point, If I have to move to a different client C (Same Employer A - on-site work at Client C Location) - in a different State - Same Job Title but different job duties/job description - Would that need to file PERM and I-140 one more time?<br>
2. Is there any language permitted in the LC for PERM - such as "relocation upon completion of the project" or "Job may require traveling/relocation across the USA" - so that the PERM and I-140 does not have to be filed again?
