The consular officer may not issue a student visa unless satisfied the applicant:
Applicants generally establish their residency abroad by presenting evidence of economic, social and family association in their home country, which indicates that an applicant would leave the United States upon completion of his/her program. Additional residency proof may include job, family and financial prospects including inheritance and/or investments, etc.
Anticipate that the interview will be conducted in English and not the native language of the applicant. The consular officer may determine whether the applicant has the necessary proficiency if the I-20 SEVIS Form indicates that proficiency in English is required. The consular officer may conduct a visa interview in English, request that the applicant read a passage written in English, or even request the TOEFL test score.
An applicant must provide documents to prove sufficient funds, to cover all expenses during the entire period of study, are available and that cash is available to cover at least the first year of study. Thus, an applicant proves he/she will not become a public charge and/or will not participate in unauthorized U.S. employment.
Due to the volume of applications received, all consular officers are under pressure to conduct a quick and efficient interview. Therefore, be brief. Consular officers usually make a decision within the first week of the interview. The applicant must keep his/her answers short and to the point. The applicant should know the program of studies and what it involves. In addition, applicants should not bring family members or friends to the interview.
Make sure you bring all original documents to the interview including the SEVIS I-20 form, I-901 Fee document, letter of acceptance, financial passport, affidavit of support, passport, and any other documents required by the U.S. Embassy.
Applicants should not argue with the consular officer. If the visa is denied, ask to the officer for a list of documents necessary to reverse the refusal and request the reason for the denial.
If your spouse is also applying for an accompanying visa, you should both be aware that dependants cannot be employed in the U.S. Also, if the dependant is going to stay in the home country, the consular officer may request proof that the applicant can financially support his/her family while he/she is absent.
Remember: The main purpose of the student visa is to study in the United States.
