<p>All nonimmigrant visas (E,H,L) are automatically terminated if the  alien   terminates his employment with his sponsoring U.S. company. If  the alien remains   in the U.S. or travels on the original visa he is in  violation of his status in   the U.S.</p>
<p>After an alien is in the U.S. under a valid E or L visa, that alien  may be   transferred to different locations within the same company (for  example from Los   Angeles to Atlanta) as long as the alien?s   job  title and duties are not changed. However, if he will work for a  different   entity (a different but related company) then permission  must be obtained from   the Citizenship &amp; Immigration Services  Office.</p>
<p>If an alien changes companies from one E sponsoring company to  another   different E sponsoring company, permission must be obtained  from the Citizenship   &amp; Immigration Services Office.</p>
