I am an international student applying for Computer Science PhD in US. Some universities I plan to apply to require Personal History Statement in addition to Statement of Purpose. I believe that I described my research interests, talents and motivation in my SOP quite well. I happen to be pretty "diverse" person as well, so I wrote about it in my PHS. The only drawback is that my PHS reveals some details of my background that may serve as a "red flag" of my lack of intention to come back to my home country after I graduate. I know this is not a good thing for visa approval, but I wonder what kind of attitude the university departments have to such students.
I received a lot of criticism for this approach. People say that I must not appear to be desperate and should avoid saying anything that is not directly relevant to my interest in Computer Science, but I believe that my history is an important part of my identity (and a chance for alternative funding sources), and I'm out of ideas of what else I can write about Computer Science that is not already mentioned by my SOP, Resume and recommenders.
So what would you suggest? Should I omit any details of my history that may raise suspision of my immigration intention?
