Please see USCIS Website for further information, see link below.
Note: The number of issued visas under the 'Limited

to the an annual numerical limitation.
Marriage is of course a way to get access to the first
category by becoming an immediate relative.
To prevent abuse
of this way, there are certain restrictions, e.g. the fiance(e)
gets in the first place a conditional permanent residence
status, which can be removed after 2 years.
