Why are some individuals able to easily obtain temporary visas to enter the U.S. while others are not?
With the exception of Hs, Ls, and Os, most other temporary visas carry with them the requirement that the individuals have only temporary intent to reside in the U.S. While applying for visas they will be presumed to have permanent intent and it is their burden to establish otherwise. Each consular official makes determination of that intent based on whether individuals can show substantial ties to their country such as property, a job, and/or close family. It is more difficult, obviously, to establish temporary intent when coming from a country with serious political or economic problems or with a high rate of emigration to the U.S. Anyone applying for a temporary visa should carefully prepare whatever documentation is available to establish such ties.
