I would suggest that the proper metric is not the number of immigrants, which after all the parent commentator implied would be the case because of higher economics drawing them in, but a combination of the following

1. the amount of violence directed against immigrants legally allowed in by governmental forces.

2. the chance of legally allowed in immigrants will have immigration status changed without due process.

3. what percentage of Immigrants fear that 1 or 2 will happen to them.

I believe these two conditions seem to exist in the United States currently, although not sure how many immigrants it affects.

I am unsure if there are other countries that have a similar situation, I would expect if there are they must be relatively few in number.

The closest type of situation would be, I suppose, racial oppression focused on particular groups that have become undesirable according to a country's government.
