Yes this is true. But i know big corp companies like Microsoft, Amazon will not withdraw approved I-140 even if you quit before completing 180 days. Just wanted to know does Mindtree Ltd revokes it or not if you quit before 180 days.
According to Frago: Companies typically don’t withdraw I140 because it looks bad for them for future petitions. They have no incentive except when it’s a small company as there is a quota for how many pending GC processes a company can have in relation to company size or revenue IIRC. And yes 180d is the legal cutoff.
The rule is 180 days (approx 6 months), and you will either need a new job offer or a new I-140 to keep your priority date. Does not apply if due to fraud, misrepresentation, etc
