Is there any restriction to the Port of Entry for H1B visa holders? Does it have to coincide with the location of assignment as stated on the LCA? What is the impact if the client were to change from A to B (the parent company/primary employer is the same in both cases) between the time of getting the H1 visa stamped and actual date of starting work in US. There is time lapse of about a year due to delays in current projects with the parent company/primary employer in India. Is a new H1/LCA required? Does the visa need to be stamped again? The H1 visa is valid until mid-2003. What questions/problems can be expected at the new port of entry?
