For non LPR You have to prove at least 10 years continuous presence, good moral character during all those years, no crimes of moral turpitude (DUIs, theft, drugs etc), and that your US Citizen or Legal Permanent resident spouse, children or parent would suffer extreme and unusual hardship if you were to be deported. The extreme hardship is really difficult to prove since it has to be more than economic or language barrier reasons usually a medical condition such as having a disabled child or a spouse that depends on you 24/7 due at an illness. Only 4,000 cases are approved per year so they're really hard to win but if you win your case you're granted a green card. Cancellation of Removal for Legal Permanent Residents are easier to win since they do not need to prove the hardship part, there is no limit on the number of cases that can be approved per year and they only need to prove 5 years continuous residence
