Working with two employers with two separate H1-Bs

[whitehorse]

Hello All,

 

I have been working with a university (Employer A) on an H1-B (cap-exempt) and recently got H1-B approval for employment with another cap-subject organization (Employer B), effective Oct 1, 2015. Unfortunately, because approval was much later, it may be that I am unable to successfully hand off responsibilities to begin working with Employer B on Oct 1.

 

My questions are:

 

1. Assuming that I do not want to work pro bono for Employer A past Oct 1, am I able to have a resignation date of say Oct 15, 2015 with Employer A and proceed with a start date of oct 1, 2015 with Employer B? Is this overlap in employment allowed, given that I technically have two H1-Bs approved?

 

2. Also, it seems that there is such a thing called a concurrent visa which appears to allow simultaneous employment. What is a concurrent visa exactly? Would my second H1-B be a concurrent visa because it was filed concurrently (when I already had an H1-B) or does there need to be a formal specification of a "Concurrent Visa" on the H1-B petition application form for an H1-B to be considered a Concurrent Visa?

 

I hope this is clear, thanks for your response!
