can the experience letter be from former co-workers who are also working for some other company now on just plain paper with their contact information or is it that experience letter has to be from co-workers who are still working with your former employer. also do you need to get degree equivalency evaluation done for your undergraduate degree even though you may have a master\'s degree from here. also can i just submit a letter from my graduate school that when admitted they had evaluated my undergraduate transcripts and degree and found to be equivalent to theirs.
