How to completely sever the father-son relationship with the biological father? (You can immigrate and apply for a green card)

Because parents and children are the closest direct blood relatives, their kinship is based on blood. The kinship of natural blood relatives is born and dies. The so-called extinction refers to the legal termination of the relationship between rights and obligations. Since the relationship with children cannot be eliminated in the case of parents' divorce, the relationship between parents and children of natural blood relatives cannot be artificially dissolved by legal means, nor can it be eliminated by newspaper statement or mutual agreement.

But in reality, the so-called severance of father-son relationship does exist, which only shows that the relationship between father and son has deteriorated to an extremely serious extent, but this behavior has no legal effect.

Because parents and children belong to the parent-child relationship in law, both parties have the obligation to raise and support, even if they are nominally separated, they cannot but bear this obligation.
