Chances of getting into the PhD program in physics and astronomy?

I apologize if that's the 100th post on this subreddit regarding this topic, but I haven't found any recent ones on the matter.

The title is pretty much self-explanatory. Is it hard for an international non-member student to get into BYU's PhD program in physics? I got 325/113 on GRE/TOEFL and has also been lucky to establish some contact with one of the professors on faculty - seems that our expertise and research fields form a good match. I got my ecclesiastical endorsement and have no troubles following the Honor Code. Talking about my background, I was raised in a non-drinking or smoking family and for the past 10 years followed a vegetarian diet.

However, am I worried that being an international student who just recently started familiarizing himself with church (after getting my endorsement I got pretty excited about the church and so far spent last few months attending regularly) is putting my chances of successful admissions at a serious risk.

Are my worries actual? Please let me know, kind subredditors :))
