The laws associated with immigration to the United States do not often see change and the number of immigrants allowed into the country each year relies on data from a 1990 law called the Immigration Act which limits the annual number of immigrants to the United States to 700,000. The law was created so as to place an emphasis on bringing families together. An immigration lawyer will be able to assist new visitors to the United States who would like to become citizens by offering representation in court and advice on how best to work with the laws and become an American citizen.
