Are you against illegal immigration, or immigration in general?

I am a Democrat (still figuring out my political alignment specifically) and I was looking for some genuine answers to this.

Recently Trump has said he is for LEGAL immigration with the Hb1 visa discussion, and people have pointed out he's always been for legal immigration, but I have also seen him generalize immigrants like Haitians for example and those from Mexico; so which is it?

It also seemed like at the time of the election his followers were against immigration regardless of legal standing and seeing the racist comments right now about Indians, having always seen them about other minorities from MAGA; now I'm seeing MAGA say immigration is good for the country when that's what the left has said the entire time.

I'm confused on where MAGA stands on with this.

For legal immigration, or against? Why is this confusing to not only me, but other followers of Trump?
