how long do facebook videos take to get reviewed for ads

[nvidia]

just hit over 11k likes on my facebook page and over 12k followers now im able to put ads on any video over 3mins but all my videos for the last couple of days say this video is pending review

anybody know how long this would take

sucks i have to wait for videos to be reviewed because by the time they are reviewed just about everybody who liked my page would have already seen the video and i will get next ad money as after the first couple of days hardly anybody watches my videos

because on facebok my videos can get like 2000+ views up yo 48k views
