You can bet that virtually no Syrian Christians will be let in. Only jihadists will be welcomed by this corrupt regime.
After scrutinizing the news, history, culture of the Mideast, I think we ought to be a little cautious about using the generic term "Christian" on those from within the Muslim-dominated areas.
I've felt strongly about this in general, and have felt the need to coin the term "Christino" or "Christianino" to cover these "Christian In Name Only" (as our RINO is used for those aligned politically but not really committed to the basic beliefs of that party).
It has recently been pointed out to me that the behaviors of Mideast "Christinos" may be not at all what a Western "Christian" might expect, but may rather be not discernibly different than that of the typical Mideast Muslim cultural neighbors.
So, please, I beg of you, don't jump to the conclusion that your statement reflects. There may be a very good reason to reject anyone who cannot easily become acculturated to the Western religious/political tolerance that our Constitution demands of its citizens (but which islamic jihadism does not).
