US immigration policy

The U.S. immigration law is extremely complex. The Immigration and Naturalization Act (INA), the body of law governing current immigration policy, provides for an annual worldwide limit of 675,000 permanent immigrants, with certain exceptions for close family members. The president and congress determine a separate number for refugees. The following determine how the U.S. immigration policy is set up; the reunification of families, admitting immigrants with skills that are valuable to the U.S. economy, protecting refugees, and promoting diversity. There is no limit on immediate relatives which include the spouse of the U.S. citizen, unmarried minor children of U.S. citizens, parents of U.S. citizen, you must be 21 to potation as a parent. There are more than 20 types of visas for temporary nonimmigrant workers. These include L visas for intracompany transfers, P visas for athletes, entertainers and skilled performers, R visas for religious workers, A visas for diplomatic employees, O visas for workers of extraordinary ability, and a variety of H visas for both highly-skilled and lesser-skilled employment. Many of the temporary worker categories are for highly skilled workers, and immigrants with a temporary work visa are normally sponsored by a specific employer for a specific job offer. The Diversity Visa lottery was created by the Immigration Act of 1990 as a dedicated channel for immigrants from countries with low rates of immigration to the United States. Each year 55,000 visas are allocated randomly to nationals from countries that have sent less than 50,000 immigrants to the United States in the previous 5 years. Of the 55,000, up to 5,000 are made available for use under the NACARA program. This results in a reduction of the actual annual limit to 50,000. To be eligible for a diversity visa an immigrant must have a high-school education (or its equivalent) or have, within the past five years, a minimum of two years working in a profession requiring at least two years of training or experience. In order to qualify for U.S. citizenship through naturalization, an individual must have had LPR status (a green card) for at least 5 years. Applicants for U.S. citizenship must be at least 18 years old, demonstrate continuous residency, demonstrate “good moral character,” pass English and U.S. history and civics exams, and pay an application fee, among other requirements.

If I am comprehending this correctly, then if you marry a legal citizen of the U.S. then you automatically become a citizen yourself? The visas are based on what you want to do when you come to the United States such as work force or religious reasons. I wonder how hard it is to get a green card and how long those last and if they vary? How to they judge “good moral character” in someone? I have looked at a few of the questions they ask you in the English and U.S. history and civics exams and I didn’t know any of them and I was born in the United States. I am also curious how much the fee is that they have people pay.
