What is the easiest way to become a permanent immigrant in the USA?

Your question requires an attorney consultation. It is not a simple question that can be answered on this type of forum. There are many factors that would need to be considered and evaluated, such as your background and whether or not even qualify for Permanent Residency. I strongly suggest that you contact an experienced immigration attorney for a face-to-face consultation and give him/her all of the facts surrounding your situation. (S)he would then be in a better position to analyze your case, advise you of your options and, if possible, make sure that the necessary paperwork and documentation is properly presented so as not to delay the process.

It is impossible to answer this question. The answer depends on the immigrant's personal background and would be to long to explain here.

There are no easy ways to immigrate as a lawful permanent resident to the United States. Eligibility can vary depending on your level of education, work experience and/or family ties to the United States.
