How did ayn rand end up in america?

After graduating college in Russia in 1924, she applied for a visa to go to America, which she got in 1925. In the beginning of 1926, she went to New York to visit some relatives, after which she was so amazed with the US that she decided to stay. She lived in Chicago for a bit, and then moved to LA. 

Explanation:

“What we take from granted in the United States as being Mexican, to those from southern Mexico, is almost completely foreign. Rural Mexicans don't have the spare money to drown their food in melted cheese. They don't smother their food in mounds of sour cream. Who would pay for it? They have never seen "nachos." In some regions of the south, they eat soup with bananas; some tribal folks not far from Veracruz eat termite tacos; turkey, when there are turkeys, is not filled with "stuffing"―but with dry pineapples, papaya, pecans. Meat is killed behind the house, or it is bought, dripping and flyblown, off a wooden plank in the village market. They eat cheeks, ears, feet, tails, lips, fried blood, intestines filled with curdled milk. Southerners grew up eating corn tortillas, and they never varied in their diet. You find them eating food the Aztecs once ate. Flour tortillas, burritos, chimichangas―it's foreign food to them, invented on the border.

They were alliens before they ever crossed the line.”
