Did you know that the average F-1 visa interview for international students is only about 3 minutes long?  In fact, student visas can be denied in as little as 30 seconds! 
We know this because we are all former Visa Officers—U.S. Government officials who stood behind those visa windows at the U.S. embassies and consulates in countries like China, India, Mexico, Brazil.  We have made decisions on over 1million visa applications, many of them for international students.  We have also seen many hopeful students have their dreams of a U.S. education dashed because they were not prepared for this short and crucial interview.  Each time a student is denied a visa, it becomes harder for them to get that visa approved.
