How do teachers write a letter of recommendation for student from teacher when the student studied undergrad in India but wants to apply for masters in the US? like is there a diff format or anything they need to follow?
TBH my prof just asked me to write a rough draft myself 
then he edited a bit and printed on the college letterhead. they mostly wanna know abt your academics, how u were in class, any projects etc. no need for some crazy format but yeah it has to sound formal.
Same happened with me 
They usually mention stuff like your strengths, communication, leadership (if any), maybe if you did a thesis or something. I think in India teachers aren’t super used to LORs for US unis so best to help them with sample points.
