Hi, i am writing this post in the hopes of have an answer if someone knows or had similar situation. I am a single mother , with sole custody for my son 9 years old, in apropiate future i am going to marry a man from uk that is resident in uae , I have read that if we move there , in order to sponsor my son with visa, or my future husband to sponsor with visa my son, even if I have a sole custody ( exclusive custody ) I still need a noc letter from biological father of my son. How does that work, I don't understand, as soon the sole custody give me the exclusive full rights to take all decision for my son why do I still need the noc letter? That is what the sole custody is for, to be able to take decisions without father's agreement. The father doesn't visit, doesn't call, doesn't send child support and of course after I asked for noc letter doesn't agree either. Am I missing something? Please , if someone knows to make it clear for me.
