Question: Person1: How do I apply to an American university ?
Person2:You should go to the library to find some information about American universities , and write to the Admission Office . Then the Admission Office will send you application forms and other related materials . From experience , many applicants write to several universities instead of just one .
Person1: I was told that it took a lot of time and effort to apply .
Person2:That is true . I'll list for you the requirements of almost all the universities . First of all , you need official transcripts of your undergraduate work , three letters of recommendation from your professors who know your competence , and the official TOEFL ( Test of English as a Foreign Language ) score ( It's usually 550 ) . Then you need a financial guarantee , and an application fee of 25 dollars .
Person1: What's to come next ?
Person2:If they agree to enroll you , they will send you a TAP - 66 Form . With TAP - 66 , you can apply for a passport from our government , and then apply for a visa from the US Embassy in Beijing .
Person1: How long will it take to go over all the procedures ?
Person2:From 3 to 6 months if everything goes well .
