I have moved from Employer A to Employer B. Actual start date with Employer B was on 03/11/2019 and I have requested them to post pone start date to 3/18/2019 and they agreed for it. My last date with Employer A was on 03/15/2019. Employer B H1B extension was approved on 03/15/2019 .
Today I got paycheck from Employer B for the period beginning 03/01/2019 to 03/15/2019. But my actual start date with employer B is today which is 03/18/2019. Is it OK to have 2 overlap paychecks from 2 employers?
