For me everything is based on how they get there and how they conduct themselves.
I have been an immigrant to several countries and I still am, but
I had all of the proper paperwork,
I didn't sneak across any borders illegally,
I didn't overstay my visas,
I didn't pay some guy on a boat to bring me there,
I didn't commit any crimes that are worse than jaywalking,
I didn't get clumped together with other people from my country and try to impose my values on the citizens of the country I was in,
I didn't do any under the table work,
I paid all of my taxes.
These are the thing that I expect from others as well.
