Withdrawal or revocation of an I-140 on its own does not trigger any sort of fraud investigation. There are some companies that sponsor a lot of aliens, and the more you sponsor by law of averages the more you will decide you don't want to sponsor, for a variety of reasons. If you are playing games, then BICE may sniff around but not for simply revoking an I-140
<<< Please understand i am talking anout only larger corporations who play by rules.If it only one or two I-40 withdrawal then it is OK but if it is lots of I140 withdrawal because of company lays off and in addition tries to substitute labor for other employees then INS may raise a flag since one side company is laying off people and other side still applying labor and I-140 for another employees. It was explained to me by paralegal of Fragomen law firm
