H1B:Can I enter US on a date past my project start date mentioned in client letter/PO

[SuddenStar]

Hi,

I had attended H1B visa stamping interview with a client letter and letter from employee and purchase order stating that the start date of my project is DateX. I am currently working with another company in India and i need to give a notice period of 3 months to resign from this job. For the same reason,

Q1) Can I enter US on a date after DateX that is indicated as my project start date or will I be rejected at the port of entry?

Q2) If after entering US, I start working with a different client under the same employer, will that be a problem later (ex: during my greencard processing)?

Thanks in advance for your advise.

1. You would need a letter stating the joining date. 2. As long as needed amendments are filed there should be no problem.
