I'm not a native English speaker, and formal letter writing classes from my school days involved archaic grammar and language. When I write a formal letter to a native speaker, I'm constantly second guessing myself to make sure I don't come off as overly groveling.
Long story short I need help to make my request letter complete. How would you suggest ending it? Any other grammatical errors? (The letter is addressed to my former supervisor)
Dear Dr. *****
I hope you are doing well.
As you may recall, I am a graduate of the ******** residency program at ****** Hospital (July 201* - June 20*5 ) I am to writing to request a letter of experience ( listing job duties, title, and dates of employment ) which is required as a part of my visa application.
