Re: English Proficiency Certificate for ×××
I have communicated with ××× in a video interview， with regular email exchange including scientific discussions pertaining to the development of his rearch proposal. I am satisfied that ×××’s abilities in the English language are more than adequate to undertake his propod duties in the Department of ××× at ××× university。 The duties will include writing scientific papers， prenting his work to an audience of his peers and participating in group discussions, all of which will be carried out exclusively in the English language.
We look forward to welcoming Mr。 ××× as visiting PhD student in our department.
Yours sincerely，
××× ×××
Professor
