Land and hold short operations

Land and Hold Short Operations (LAHSO, pronounced "La-So") is an air traffic control procedure for aircraft landing and holding short of an intersecting runway or point on a runway, to balance airport capacity and system efficiency with safety. 
Its use is voluntary: if a pilot denies LAHSO clearance the Air Traffic Controller must revector the aircraft to ensure adequate separation from other aircraft landing or departing an intersecting runway or crossing down field. A heightened level of situational awareness is necessary, and student pilots or pilots not familiar with LAHSO should not participate in the program.
Although used in the US, many countries do not permit LAHSO clearances, and some airlines' operating procedures do not allow their acceptance in countries that do permit them.
LAHSO was previously called SOIR (Simultaneous Operations on Intersecting Runways), and incorporates and expands all SOIR definitions.
Types.
There are three main types, to land and hold on the runway:
Requirements.
Non-air carrier aircraft: ceiling 1,000 feet and visibility 3 statute miles. 
<br>
Air carrier aircraft: ceiling 1,500 feet and visibility 5 statute miles, unless the landing runway is
equipped with precision approach path indicator (PAPI) or visual approach slope indicator (VASI), in
which case 1,000 feet ceiling and 3 statute miles visibility must be applicable. For configurations requiring a
RLP, the ceiling and visibility may differ.
