The Immigration and Naturalization Service of The United States works primarily to ease the entrance into the United States of those people from other countries who wish to either visit, apply for a working visa, or to become permanent residents of The United States. Those laws that govern the entrance of people who are willing to give up their citizenship to the country of exit and accept the citizenship of The United States are different from the laws that apply for temporary work permits or for visiting status to The United States although both situations are governed by the same agency known as the INS.

When industries recruit workers from other countries who are specialized in a field that is difficult to find workers in The United States, they do all of the contacting with the INS and arrange for their recruit to enter the country for a specified amount of time. Occassionally, such a specialized worker can apply for permanent residence to The United States and get a green card. Without the issuance of a green card by the INS to a person in The United States, that person has to abide by the time limit of his work permit for the job that he was hired to do.

That situation does not apply to those individuals who enter The United States without a work permit issued to him by the INS. If you enter the country without a visa or temporary visa issued as a work permit, you are in the country illegally and can be immediately deported. Simply because the borders of Mexico are with the United States does not mean that border jumping is legal. The United States also shares borders with Canada, and the same laws of legal entry via visa are required as they for those coming in from Mexico. Dire need as is often used as an excuse to enter the country illegally is actually ludicrous. Welfare assistance can be applied for in Mexico from the Mexican government of which they are citizens.

Jobs in The United States are technically a situation of qualified worker and job. Certain high tech industries that look overseas for workers may be overlooking workers in the United States for many obvious reasons. A qualified worker in the United States expects certain perks and incentives that a worker from overseas may not even be aware of or even care about if his interest is in getting into the United States. Those workers get paid a salary that is perhaps more than he would get paid if working in a similar line of work in his country. In similar fashion those who risk their lives to jump the border from Mexico to the United States get paid a salary that is more than they would get in their country. The only difference is those workers who are recruited get an entrance working permit from the INS, are known citizens of another country, are documented temporary immigrants while those who jump the border can be escaped convicts from a Mexican prison for all anybody in the United States including those people who hire them, know.
