After evaluating all the option I felt the best thing is to apply for PRTD for my wife and son on H&C grounds, If it's get approved, then I will apply for visit visa for my younger son. if PRTD get refused, then i think thier PR gets revoked? Just want to know if IRCC gives them a chance to apeal ? will they get visit visa to canada? otherwise I have to sponsor them again, the only issue is the timeline I don't know how long it takes and I have to stay away from my kids, but this is the price I have to pay þ the past mistakes of not maintaining my PR amd residency obligationThank you @armoured for details amd valuable response, this will help me and other members
Thank you very much
