According the UN. and it's declaration of Right of Foreign nationals in an other country you are entitled to:
1. Aliens shall enjoy, in accordance with domestic law and subject to the relevant international obligation of the State in which they are present, in particular the following rights:
(a) The right to life and security of person; no alien shall be subjected to arbitrary arrest or detention; no alien shall be deprived of his or her liberty except on such grounds and in accordance with such procedures as are established by law;
(b) The right to protection against arbitrary or unlawful interference with privacy, family, home or correspondence;
(c) The right to be equal before the courts, tribunals and all other organs and authorities administering justice and, when necessary, to free assistance of an interpreter in criminal proceedings and , when prescribed by law, other proceedings;
(d) The right to choose a spouse, to marry, to found a family;
(e) The right to freedom of thought, opinion, conscience and religion; the right to manifest their religion or beliefs, subject only to such limitations as are prescribed by law and are necessary to protect public safety, order, health or morals or the fundamental rights and freedoms of others;
(f) The right to retain their own language, culture and tradition;
(g) The right to transfer abroad earnings, savings or other personal monetary assets, subject to domestic currency regulations.
And that's about it. Of course, only UN member countries are bound to follow these statues. But some still don't.
Nothing there about employment, voting, private ownership, health care, and many other things we take for granted.
of Course this is made more complex in SR and the SIN system... cause if you don't have a SIN, it's hard to prove you are even alive... ESPECIALLY when there are people looking for organs, lab rats, dinner, and target practice... ("Did I
really kill someone? Prove it. Where were they born? to Whom? What Hospital? Who knows them?")
Nowadays, you can get away with not answering simple question like your name, DOB and such (they charge you for it..) But it makes the authorites go to extreme lengths to find out about, often turning to the public for help.... In SR, they turn to your SIN and the GSR with a DNA sample..... But.. you... don't .. have.. a .... SIN..... And since every citizen born to a country is supposed to be in the GSR.... that can mean only one thing.. you're not real!
