What does a visa denial under INA section 214(b) mean?  

This law applies only to nonimmigrant visa categories. If you are refused a visa under section 214(b), it means that you:  

Did not sufficiently demonstrate to the consular officer that you qualify for the nonimmigrant visa category you applied for; and/or Did not overcome the presumption of immigrant intent, required by law, by sufficiently demonstrating that you have strong ties to your home country that will compel you to leave the United States at the end of your temporary stay. (H-1B and L visa applicants, along with their spouse and any minor children, are excluded from this requirement.)  What are considered strong ties to my home country?  Ties are the various aspects of your life that bind you to your home country. Strong ties vary from country to country, city to city, and person to person, but examples include:  

Your job; 

Your home; and/or 

Your relationships with family and friends. 

While conducting visa interviews, consular officers look at each application individually and consider the applicant's circumstances, travel plans, financial resources, and ties outside of the United States that will ensure the applicant’s departure after a temporary visit.
