I work for a startup (abroad), that doesn’t have a letterhead at the moment. The director of the company, to whom I am directly reporting to, has provided a print-out of the reference letter (with the company logo) I needed with my job duties and all the other information needed.
The letter has also been sealed using the company seal, with my director’s email and phone number mentioned at the end too. Will this be sufficient? Or do I need to get it notarized before I submit it to OINP?
