Dear Prof. Xxx,
Please excuse me for bothering you.
My name is xxx, a xxx in University of xxx, USA, working
on xxx.
Due to my expiring visa, I cannot continue my current work in the US after
xxx. So I am applying permanent residency in the US, which would make
my continuous research work in the US possible.
At the request of the US Immigration office,
160;I should demonstrate the significance of my work evaluated from
independent, prominent scientists.
One of my studies focused on xxx. My findings in this area were published in
top journals like “xxx”, “xxx”, and “xxx”.
I know that you are a leading authority in xxx, so I am writing
160;with greatest sincerity and timidity to
ask you for a big favor of writing me a
reference letter about my research work mentioned above. Your reference
would help me out of the visa difficulty.
I have attached my CV in this email for your review of my research
experience and my qualifications for application.
If you would kindly write me the letter, and if you prefer since you are so
busy, I will make a draft of the letter
160;for your reference. You letter would be of
;great help for my application. And this letter will be used
for permanent residency petition ONLY.
I completely understand you are extremely busy, so it is fine you need a
couple of weeks to fit it in your schedule. Also please do feel free to let
me know if it's not convenient for you to write this letter.
Sincerely yours
xxx, Ph.D.
University of xxx, USA
