There is nothing unethical or immoral about immigrating to another country. If a foreign national finds an employer that wants to hire him or her, a landlord that wants to rent to him or her, a homeowner that wants to sell to him or her, etc... as far as I'm concerned they have just as much of a right to be here as anybody else does. If you think you have the right to use the filthy, bloody, weapon of politics to attack immigrants/business/citizens simply because they want to peacefully interact with each other without your little mark of the beast, YOU ARE SCUM. Don't take this personally, I was in the same boat with you at one point, then I thought and matured a little and eliminated this fascist philosophy from my mind.
