I graduated last May and I wonder how I should ask professors for recs because most of them I only took one class with. The one I did research lab with, well she was on sabatical because of pregnancy and the graduate student back then only communicated with her through email. I tried emailing her numerous times since the R.A position (Spring 07') up until now, she never responded any of my emails. Does that mean I should not approach her in person? (She just resumed teaching this past Fall) I mean, would it means she doesn't want to write one for me and even if I approach her she would say, "Oh, I don't know you, I've never worked with you before."
Is emailing not the best way to approach professors? I mean even to tell them that I am an alumni and would like to schedule an appointment to discuss the LOR?
Or I should just find out their office hours and go back to campus and walk-in their office and talk to them about it.
Some schools say if you have been out of school for some time I may get a LOR from supervisor/employer. How long is "some time"? Would I qualify that status...is LORs from employers not really preferred?
