I just immigrated to America and want to go to college. ...

1。 There are many public universities in America whose tuition fees are not very expensive. You can go to a community college for two years and then transfer to a regular four-year university. In that case, the tuition will be cheaper.

2。 I don't think you need to go to preparatory school. If you are not sure about your English, you can take some English courses in the community college, for example, for one semester. But I don't think it is necessary to study for a year or two. I think English class is a waste of time. With the increase of your class time in America, your English will improve gradually.

3。 There should be many good universities in new york.

4。 At present, the spring semester of most schools in the United States will end at the end of May, so you can't enroll until September.
