A visa is not your permission to enter the country.  it is merely your authorization to board a plane heading to the country and stand before the immigrations officer.  the immigrations officer has every right to refuse a visa holder based on any number of reasons.  this was the case long before 9/11.

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

That depends on where you live.  From some countries, there is no way to get a visa to the USA unless you're invited by or marry a US citizen, or are employed by a company in the USA.  Your best source of information would be the US Embassy in your country.  For a list of Embassies, see this page:\n\nhttp://travel.state.gov/travel/tips/embassies/embassies_1214.html

You should go to your embassy and apply for a visa. While you are there they will give you instructions on what you need in order to apply for this visa to visit other countries. Some countries will allow you to visit, if you don't have any intentions of staying in the country illegally and also if you have family to visit for a short period. There might be a long waiting period, but in the mean time make sure you are lawful in your country and you have the finances to cover the fees involved.  You may also have to travel to other countries before you can come into the US. You sometime is required to show that you are a tourist and you are not trying to leave your country. I hope I was helpful.

There are no such requirements for immigration to the US.  If you're talking about not being able to qualify for a /us tourist visa, then just getting a job or buying a house in your own country won't work either.  The interviewing officer needs to be convinced that you intend to visit the US for a short time and then return home.  If you can't convince him or her of that, the law says your application must be refused.

Not too sure because rules are strict regarding immigration.\n\nBest way to find out : dial 211 : it is a free phone number to get answers like that.

It is considered an "illegal-alien" or "out-of-status visitor."\n\n"Staying beyond the period of time authorized, by the Department of Homeland Security, and out-of-status in the U.S., is a violation of U.S. immigration laws, and may cause you to be ineligible for a visa in the future for return travel to the U.S."\n\nPlease read the following website for more info.

some people come here legally with student visa, tourist visa. Then stay here ILLEGALLY after their visa has expire.\n\nThose who come here with student visa are smarter.

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

I have the same question for anything that involves a 'pass'.  How do you enforce their leaving?  Right now up to half of the people here came legally and overstayed visas.  Why would these passes miraculously be enforced?

It depends onwhat kind of visa she is entering the country on. Is it a visitor's visa? Employment? Student? Without more information, this question cannot be answered. It could matter that she declared bankruptcy because some visas require a certain amount of investment in US business. Others only permit a short stay so the home country happenings do not matter.

If your friend is out of the country, he can go the nearest American Consulate or Embassy in the country he is in.\n\nA nonimmigrant person temporarily enters the United States for a specific purpose such as business, study, or pleasure. When he entered the country as a nonimmigrant, a U.S. immigration inspector should have examined his passport and visa and then given him a Form I-94 (Arrival/Departure Record). This record should tell him(in the lower right-hand corner) when he must leave the United States. If he wants to extend his stay in the United States, then he must ask for permission from the US Citizenship and Immigration Services (USCIS) before his authorized stay expires. Proof that he is willing to obey U.S. immigration laws will be important if he wants to remain or travel to the United States as an immigrant or nonimmigrant in the future. If he breaks immigration laws, he may also become subject to removal (deportation) so it is very important that he does this before his visa expires.

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.

You can't.  Entry to the US under the Visa Waiver Program precludes your applying for an extension of stay or change of status.

I am sure it has ALOT to do with the would-be visitor's country of citizenship. For example, visitors from many middle eastern countries, as well as N. Korea can probably expect more difficulties entering the US. However, any visitor can ride an elephant from Nuevo Laredo, Mexico preceded by a marching band into the US without papers, passports, or any unnecessary wait time. This is much faster than hiring an attorney!
