How is immigration now in the us the same as immigration in the 1800s?

Before 1900, there may have been some marginal fiscal gain from immigration. Today, the estimated annual net cost of each immigrant, on average, is $2700. Then, immigrants' stay in the U.S. was often temporary; today's immigrants are here to stay. The Immigration and Naturalization Service estimates that the rate of return from 1900 to 1904 was over 37 percent 3; in the 1990s, the rate of immigrants' return to their homelands was a much lower 15 percent. During those frontier days, we had a vast empty country and states actively recruited immigrants. Now, our country is increasingly congested and communities pass ordinances to limit the growth of their populations. In 1900, the number of people per square mile in the United States was 25.6; in 2002, it was 82 people per square mile—a more than three times greater population density.  At the turn of the last century, having relatives in the United States made it logistically easier to immigrate here; it did not, however, guarantee that you would be admitted. At the turn of this century, having near relatives in the United States makes you legally eligible to immigrate and guarantees you eventual admission. In 2001, 64 percent of legal immigrants were admitted simply because they had a relative here. Due to the eligibility of the foreign relatives of immigrants, there is a line of several million aliens waiting and eligible for admission as immigrants to the United States.
