As an immigrant in this country, which I have chosen to live in, for a better life, how could I even attempt at commentating on someone else wishing to do the same.
Passports and visas are a relatively new condition to travelling. The various politicians who passed the immigration laws are the ones who suddenly made it illegal to travel a world that we all live in and fundamentally have a right to live anywhere in it.
"illegal" immigrants do not claim dole or other monetary gains and invariably live in squalor and work for peanuts, doing jobs that the 'indigenous' people won't do.
