Hello Sir, Thanks in advance for your help. My I-140 was approved for company A in 2010.Before and after that I have been working on h1b but at company B. In 2011 company B obtained an H1b extension for 3 years. Meanwhile in 2012 company A was sold to company C. Company C however have not yet obtained new 1-140 via successor in interest. My H1B is now due for renewal in 2014 and company B like to extend it.Will this extension need company C to obtain successor In Interest first and then only company B can apply for H1b extension or Company B can make an extension petition based on original 2010 I-140 approval for erstwhile company A which does not exist now? Kindly advise.
