Thank you,

but sorry I can't help your request, for I signed the contract with lawyer, those reference letter can not be spread to third party, basically I don't have the right to give any body the letter sample, even I think it is not too much difference from one to another.

I can introduce you to my lawyer if you want, he is a patent lawyer, and do this immigration case on spare time and only take case by friend reference. I have already refer 2 people to him, even I think the lawyer owe me referral fee :-)

all I care is paying lawyer money by saving my research time.
