Canadian generally get special tratment in the US, they can work and study without a visa as long as they have the proper paperwork to show at the US border. Check NAFTA requirments for that.\n\nAs far as just visiting the US, it's normally no more than 6 months in a year (total) ,however, that is very hard to enforce. You have to just be carefull when you enter US again. If the border officer suspects that you reside in US permently he will deny you entry... so just be careful what you say and you should be fine

Why not ask the U.S. Immigration Authorities or an attorney specializing in immigration law.

I'm sorry I can't answer your question very well but I know that there are states out there that do.  In North Carolina, for example, you have to prove residency and identity.  It would be really hard, almost impossible, in fact, to have the items on their list of accepted documents unless you are legally in the country.  If you weren't born in the US or Canada then you have to have multiple things like valid passports and school records.

Only people with visas require re-entry permints.  As a Green Card holder you're a permenant resident and can come and go as you please.  That is as long as you have a valid passport from your country of origin.

Well, the American person can re-enter whenever since that one is an American citizen. As for the Canadian, that one can come in on a travel vise, but can't work unless that person has a sponsor or is married to an American.\n\nAs for phone numbers, this is a good place to start:\nhttp://www.uscis.gov/graphics/services/NCSC.htm

Whether or not a visa is required depends on the traveler's actual citizenship, not the fact that he or she has a US green card.

anyone who can meet the citizenship requirements is entitled to become a citizen. illegal entry should eliminate them from qualifying for a period of 5 years AFTER their deportation and subsequent LEGAL entry into the usa.

Why do people just make up stuff if they don't actually know?  Go to http://www.travel.state.gov/travel/tips/brochures/brochures_1229.html\nfor foreign entry requirements.  It tells whether you need a visa and how to get one for every country.  There are dozens all over the world that don't require visas of US citizens.

Yes, U.S. citizens don't need a visa as we are neighbours but anyone else in the world is required to have a visa or passport.

I found this}}}   EWI: or Entered Without Inspection, means entering the United States without being inspected by an Immigration official.  Most commonly this means crossing the Mexican or Canadian border without having any contact with an Immigration official.  A foreign national who enters the U.S. EWI generally cannot apply for legal status from within the United States, with the exception of asylum applicants and individuals with applications for adjustment grandfathered in under 245i.\n\n Try browsing more in this site. I'm trying to find that info myself

International Travel\n\nA Permanent Resident of the United States can travel freely outside of the US. A passport from the country of citizenship is normally all that is needed. To reenter the US a Permanent Resident normally needs to present the green card (Permanent Resident Card, Form I-551) for readmission. A reentry permit is needed for reentry for trips greater than one year but less than two years in duration.

A citizen of a foreign country, wishing to enter the U.S., generally must first obtain a visa, either a nonimmigrant visa for temporary stay, or an immigrant visa for permanent residence. The type of visa you must have is defined by immigration law, and relates to the purpose of your travel.

Good question - First of all the visa issue is a two way street - that is when applying for a visa to the USA the individual has to get the permission from their own country first.  You just do not walk down to the local airport in China and caught a flight out without permission.  After they obtain their governments permission then they can go apply to the receiving country.  Most countries in the world have similar processes especially if they are planning on staying awhile.  However, some countries have no process and actually print comic books on how to enter the USA without any paperwork and how to apply for social benefits once they get there.  China is not one of these but Mexico is one of these countries.

Once every year the US Immigration holds a "lottery" for entrance into the US which includes a Green Card. This lottery is run during the late summer, you can find out by contacting the Major Newspapers in your area, as the US runs these ads during that time. You will have to qualify  . Good Luck!
