Question details
What is the chance for a L1A visa holder of 7 years to qualify for a EB1 category. Catch here is the original company which provided the L1A visa will not apply for GC. If the person moves to another company on H1 Visa can the new company file for GC under EB1 based on the previous 7 years of L1A status .
ANSWER
No, sorry. The basis of an International Manager's or Executive's EB-1 filing is that you must have been employed abroad with a related company for one year. Since you will not be able to meet that criterion, I do not see how that type of EB-1 can be filed through a new company.
