What unpopular common sense should I know if I want to study in the United States more smoothly?

1, electricity consumption The voltage in the United States is 1 10V, and that in China is 220V. Therefore, household appliances with working voltage of 220V are generally not available in the United States, and heating equipment is likely to be available. However, serious undervoltage protection will shorten the service life of the equipment, and household appliances with 1 10V-240V responsive power supply can be sent to the United States.

The layout of the three-phase plug in the United States is the power supply of most desktop computer cases, that is, a cylindrical pin and two parallel flat pins, which is completely different from the common three-phase plug in China. The two sockets of two-phase power sockets in the United States are different in size, one side is slightly larger than the other, but it can adapt to the two-phase power plugs in China.

2. Payment method Bank credit cards are widely used in the United States, but you still need to prepare some cash in advance. Because some businesses only accept cash payment below a certain transaction amount in order to evade taxes. In order to establish your own personal credit record, it is suggested to apply for Bank of America to issue a bank credit card as soon as possible. If you apply for a savings card first, friends should remember that you can't use a savings card for online transactions.

3. If you don't use a telephone line to surf the Internet, you can buy a mobile phone directly, and you can easily dial a cheap IP calling card with your mobile phone. In the United States, mobile phones are charged free of charge according to the service plan. If you think the mobile phone is not free, you can buy one yourself. Smartphones cost about $50/month. It should be noted that the phone bill beyond the completely free min part is too expensive, 40p /min, so friends must be careful not to "explode".

4. Basic knowledge credits and graduation rules for studying in the United States. If you want to graduate from an American university, you only need compulsory courses and elective courses *** 120 credits; Graduate students are divided into two types: taking credits (36 credits) and doing scientific research and writing graduation thesis. Training fees are also paid according to the number of credits. The course content doesn't pass, so you must take the exam again. Less than 70% of American students graduate (such as Bill Gates and michael dell), and it takes an average of five years. Immigration law requires international students to take at least 12 credits every academic year. Because many colleges and universities also offer courses in summer, it only takes three years to graduate from colleges and universities.
