URGENT -- Can I use old and valid H1 petition to start job?

[tejas24478]

I got an approved H1 petition from Employer A while I was in India.

Then I got another approved H1 petition from employer B and then travelled to USA on that petition (employer B).

Now, my job with employer B in USA is about to be over and I am trying to find another employer in USA.

My old petition with employer A is still valid not cancelled(not revoked).


Question 1:
----------
Can I use the same old petition and start working for employer A right away?
OR
Are there any complications involved?


Question 2:
-----------

Does employer A need to file a new LCA if I want to join them on an already existing approved H1B?
OR
Can I simply join them and get the payroll started?



Please let me know urgently as I have very limited time left to make decision..

From when to when A's petition was valid? As a new LCA would be required because even if job location, role etc remain same, am sure over 3 Years the salary levels have changed so a new LCA and an H1 amendment would be required.

This is my opinion not legal advice.
