US Visa Thailand - F1 Visa Thailand

F1 family visa is for unmarried sons and daughters of US citizens.  There is an annual quota of 23,400 visas available in this category worldwide plus any numbers not required for fourth preference (F4).

F1 family visas allow the holder to receive a US green card.  However, the wait for F1 family visas to become available takes many years (5+).  Thus, the F1 family visa is only an option for applicants who do not need to travel to the US in the near future. 

The US State Department maintain an updated monthly list of the wait times for family visa applications.  The monthly list of wait times is called the "Visa Bulletin" and can be found at http://www.travel.state.gov/visa/bulletin/bulletin_5518.html. 

The Visa Bulletin will show various dates under each family visa category (F1 - F4).  The date listed therein is the date in which the applications they are currently processing were filed.  EXAMPLE:  If the date under F1 family visa category says 01 May 2004, then such means the wait is approximately 7 years from the date of filing assuming today date is 01 May 2011.   

Please  note that once you apply for a F1 family visa that such applicant would not qualify for a tourist, business or student visa because such visas require an intent "not" to immigrate to the US.  By filing the F1 family visa application you are declaring you have an intent to immigrate to the US and such makes you ineligible to receive a "temporary non-immigrant visa" such as tourist, business or students visas.
