Time of processing for family re union visa

Please what is the during of processing for a family reunion visa when children are going to reunite with thr father (a belgium national)?

Generally, nowadays it takes upto 6 months for family reunification. And based on the nature of the file and the volume of investigations that the foreign office needs to make on the application.

OK thanks
