All imports are "cheap" whether labor, steel or iphones. Cheap is good, because if you can get something cheap it means you can get it with minimal resources.

The only reason to limit immigration is externalities. For example, Israel has very open immigration for Jews. It does not allow open immigration for African refugees because they believe it would have a negative impact on their society. For some strange reason, other nations are fearful of stating the same thing, but they clearly have something like this in mind when they limit immigration.

Cheap labor is a net positive. The only valid reason to oppose immigration (and I think it is very valid) is the negative social externalities that immigration causes.
