<human>: My boyfriend and I are both 17 years old, and we have been dating for about four/five months (which is a long time in the high school world) and are now pretty serious. 

He is from Syria and only came to the US last June because of the recent conflicts, but his parents as well as the rest of his family stayed in Dubai. 

Recently, they have given him the choice of going back to Dubai or staying California. Obviously, I really want him to stay not only because I would miss him if he left but because I also think it is what is best for his future. 

He says that his heart wants to stay in CA, but because of academic/economic reasons it would be more logical to go back. For example, he loves playing football and would have to give that up if he left. Also, in Dubai the lifestyle is different - he would most likely go back to smoking cigarettes and living a "party" type of life. 

His main concern are his grades - he wants to be a dentist and to go to a good program in college, but we go to a very challenging prep school in Silicon Valley and his grades are not as good as they were back in Syria. I have offered to help him study in all of his classes in addition to helping out with SAT/ACT prep, but I'm not sure if that's enough. 

Do you have any advice on how I could convince him to stay? Thank you! :)
