I suggest you go into battle with less luggage and buy it there. Prices in the United States are a little cheaper, and people in China buy these daily necessities. Carrying too much luggage is not only expensive to check, but also imaginative. . . You are a girl in an unknown American airport. Don't you think it's terrible to face this pile of luggage? American time is not divided into cities, just like China uses Beijing time and Japan uses Tokyo time, but the latitude of the United States is relatively large, so it is divided into three time zones, eastern time, central time and western time. Just look at the location of Minnesota on the map. Moreover, I remember that the iphone automatically changes the time zone, so you don't need to adjust it yourself. The visa should be at least three or four months in advance, and the air ticket must be booked first, otherwise the visa will definitely fail. However, this is easy to handle. Find a travel agency to help you make friends, so you don't have to worry about not meeting China people. There are many Americans here, and they are relatively easy to get along with. As long as you take the initiative to communicate with them, you will not be rejected, a little familiar, but divided. People born in the United States will be more communicative, and people born with golden spoons will have a heavier racial concept, but 95% of the United States is middle class, so don't worry. According to my personal experience, it's best to pretend to be forced first, talk less, make a fuss, and you will talk less. . . Calm down for a few days, but don't be cold to people who offer to be nice to you. I mean keeping a low profile for two days, not two days of autism. . . Get to know the characters of people around you in a few days before you let go. At the same time, people around you will be more curious about you, and others will be more willing to make friends with you at this time. Personal experience is for reference only, but maybe there will be a Shanghainese or Beijinger in your dormitory at that time, right? Don't worry, when you cross the bridge, it will be the highest level of life. It is more cost-effective to find a friend who rents a house or something. It is not recommended to work during school, except in winter and summer vacations, especially manual labor, because everyone's main purpose is to study, and it is difficult to graduate from work every day. The best way is to apply for a librarian or dormitory manager to help the school work, which can save you a lot of money and accommodation in the school, but this position is still competitive. Anything else you want to know, just ask ~
