One of my friend is applying for PERM. There is problem withh his experience letter. He has experience letter from his privious employer with end date as 10/31. He joined New employer at 11/07. Privious employer is not ready to give him experinece letter with date ending at 11/07 even though he worked for him. Will ther be any problem with this 7 day differnce in future. Please advice.
