US Visa Singapore

F3 family visa is for married sons and daughters of US citizens.  There is an annual quote of 23,400 visas available in this category plus any numbers not required by first (F1) and second (F2)  preferences. 

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 on the US Department of State website.  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. 

Please  note that once you apply for a F3 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 F3 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.

F3 family visas allow the holder to receive a US green card.  However, the wait for F3 family visas to become available takes many years (10+).  Thus, the F3 family visa is only an option for applicants who do not need to travel to the US in the near future.
