Hello,
I have been trying to get a concrete answer for my situation, I would appreciate any help.
(1) Joined Company A in 2008. Started on H1b on 1st October 2009. I-140 was approved in March 2011.
(2) Joined Company B in October 2011. H1b is valid till October 2014. Currently waiting for PERM approval with Company B.
(3) Looking to join Company C in June 2013. I am trying to find out what would be the validity for the H1b transfer. Based on my initial H1b start date of 1st October 2009, I will finish my 6 years of H1b on 30th September 2015. However, I was also told that since I have an approved I-140, I can get a 3 years extension. Hence, I might get my H1b with Company C until June 2016. The second scenario would give an additional 9 months. My only concern is whether or not I am eligible for the 3-yr extension since my I-140 was approved with Company A and not Company B.
Thanks for your help.
