The Church’s policy actually seems to be anti-immigration. Sure the Church doesn’t get involved in very many political issues but this one is an exception.
The Church has made no public statements that I can find on the issue of immigration, especially as it applies to the current political debate. But the Church has made it abundantly clear about the attitude of saints immigrating from other countries. The Church has "encouraged" it’s members to remain in their own countries to help build up and strengthen the Church.
That policy creates some questions in my mind. Members from other countries want to immigrate to the US for various reasons. These reasons include a better life for them and their families, more opportunities! The Church is stonger here, this can benefit them and their families as well. Getting to participate in all the Church programs, with peers who have similar standards can strengthen individuals and give support when needed.
Sure I’d admit that in small branches, small wards, developing areas, there is great need for leadership and strong members. There are more opportunities for missionary work and maybe even more service.
But what’s more important here, saving the individual…and the family, or making the Church stronger? Yes, yes, I understand we can’t have all these converts coming the America and leaving the mission field in shambles. The policy makes sense in a macro viewpoint, but if it were me, and I had to choose—I’m sorry I’d probably choose for my family.
