The J-1 visa obligates (强制) the student to return to their hime country for a minimun of two years after the end of their studied in the US.The B-2 visa(Tourist Visa) is not considered a student visa for full time study. As a general rule, if you intend to enter the US as a student, you should get a F-1 or J-1 visa.To get a visa approved, you will need to show that you have enough funds to pay for the first year of study and that you have resources available to cover the rest of your educational program. The information you provide on the I-20 form (F-1) or IAP-66 form (J-1) will be examined very carefully by both the foreign student adviser at the school and the INS. If you don't have the resources necessary for study in the US, you will not get a visa. If the foreign student adviser believes you have the resources necessary for study in the US, he or she will send you a Form I-20 (Certificate of Eligibility for Non-immigrant (F-1) Student Status). You will need to submit (递交) this form with your application for a student visa to the American embassy (大使馆). If your education will be sponsored （赞助）by a US citizen (e.g., a relative), the relative will need to fill out a Form I-134 (Affidavit of Support) .This form requires them to pay your expenses if you can not. A form I-134 filled by someone who is not a relative does not count as much as a Form I-134 filled by a relative.  76. What is the best title for the passage?       A.
