Immigration law covers all issues pertaining to foreign nationals coming to this country either temporarily or permanently, and the associated legal rights, duties, and obligations of aliens in the United States. Those issues include the application processes and procedures applicable to the naturalization of foreign nationals who wish to become U.S. citizens, as well as people who cross U.S. borders by means of fraud or other illegal means.
It might seem sensible to rely upon the government agencies that administer immigration for help and advice. However, these agencies have no responsibility to you for information they provide and are not trained or equipped to give you reliable information.
