These are people who were either born in the U.S. or who have become "naturalized" after three or five years as permanent residents. These citizens can never be deported, unless the citizenship was obtained through fraud. You can work legally and receive any public benefits you qualify for. In addition, you can petition for the legal status of your spouse, child, parent or sibling.
To convert your conditional status to permanent status, you will need to submit a Petition to Remove the Conditions on Residence (Form I-751), with supporting evidence and the appropriate fees, up to 90 days before your conditional residence status expires. If you apply before the 90-day limit, the application will be returned to you. If you fail to file before the two-year anniversary, your card and your conditional residence status will both expire and you could be deported. You have a three-month window to file your application. You must submit, in a timely manner, the application, the appropriate filing fee and any supporting evidence in order to qualify.
Both types of residents have permission to live and work permanently in the U.S. unless they are guilty of a serious criminal offense or some other immigration violation. If you are a resident, you can also petition for legal status for your spouse or child.
Generally, if you have been a lawful permanent resident for five years, you can apply to become a naturalized U.S. citizen. But if you were granted a green card based on marriage to a U.S. citizen, then you can apply after three years. Just because you received a green card doesn't mean you will automatically become a citizen. You have to show that you deserve it. If you were arrested for any reason, if you owe any taxes or have failed to pay child support you should discuss your matter with an immigration attorney before filing.
People who fall into this category are in the country legally, but only on a temporary basis.
Examples include:
� students (F-1 visa)
� business visitors or tourists (B1/B2 visas)
� fiancées (K-1 visa)
� individuals granted temporary protected status.
In general, recipients of these visas don't intend to immigrate. If the application is fraudulent or you overstay or otherwise violate the terms of the visa, your legal status will change to undocumented. Even so, a high percentage of undocumented immigrants came on legal visas.
People who are in the country without permission, or illegally, are called undocumented. This means they do not have permission to live in the U.S. They are not authorized to work and they have no access to public benefits like health care or a driver's license.
Any person who is undocumented runs the risk of being deported or having deportation proceedings started against them at any time. This creates a highly stressful and unstable living situation.
There are two ways people can become undocumented. The first, as was the case with my family, is to overstay a legal temporary visa. The second is to enter the U.S. without going through a port of entry.
