H1B extends-after 11 years

[mohan656]

Hi,

 

I am currently working company B using Company A Approved-I-140 -PR-date #01/07/2012 long waiting years. I left company A then moved to Canada using PR and re-applied Company B using Approved I-140 and got new H1B until -01/2020.  Current Company -B told that they will start Perm and I-140 within 6 months but now they yet to start and it may take another 10 months.

 

my question is if i leave company B and can I use my exiting I-140 approved  get H1B exn if i want join later to C ? or company need to file Perm and I-140 approval required.

 

Company A- 140 approved 2013 and worked for company A for almost 5 years after approval.

 

Kindly advice and Thanks for help in advance.

 

Regards,
