There are many visa applicants who lie during the visa interview and present fake documents. Remember the interviewer is trained for his work so any lies about anything may lead to a rejection of the visa. If you present any fake documents regarding financial situation or academic grades not only your visa can be rejected but you might also be barred for visa for a certain period of time or even worse forever. Hence never present any fake documents. In some cases the visa has been revoked even after a visa was granted. The decision was taken after it was found that some of the documents were ‘fake’ and hence visa revoked. Such cases have been found normally in those cases where a student was not awarded funding and hence in order to show the sufficient amount of money in his account, the student took the help of some private agency. Such agencies put the required amount of money in your bank account until your visa interview is done and charge some price for it.
Not always however the fake documents are identified but refraining from any unlawful act is certainly an advisable idea. Sometimes visa applicants lied about their relatives and siblings being in USA. They think that if their siblings are already in USA their visa might get rejected as visa officer might think they are planning to settle down in USA itself. However this is a misconception. In fact, every visa application is viewed as completely separate to other visa application and it doesn’t matter if two siblings are applying for a visa same year. There are several such cases when two siblings have been approved visa at the same time. Hence one should not lie about anything. If you have any close relative or siblings in USA, reply honestly. More often than not this is not going to affect your chances of getting visa approved. However if you are found out lying it’s almost certain that your visa will be denied.
Once you have a successful visa interview the interviewer will keep your passport. The passport with the visa on it will then be sent to your address through courier. You will need some valid document in order to collect it like driver’s license, taxpayer's ID or some other valid photo identity card depending on the country you live in. Once you get your visa, you can start packing. The next step will be preparing for your long awaited journey to United States of America.
