No he's not a US citizen, but a canadian citizen like myself, the rest of his family has a US citizenship. and he wanted to marry a US citizen because it is easier for him to move there apparently as she can sponsor him. We're both Indians  and from the same city there, both currently living in Canada as Canadian citizens. so in our case, we are both from the same culture and our parents are family friends and very open minded allowing us to choose our partners. but in his case he just had a player mentality, selfishness and lack of empathy over someone he was talking to for so long. he chose to go with the other girl as he started talking to both of us just recently without either of us finding out, he knew he would marry her but continued to keep me in the dark because he did not want me to leave him before he confirms things with her.
