Hi Joey
Sorry to read of your situation.
As stated earlier I think you need to consult with a professional to find the best way forward for you. Lack of information regarding your situation and your children's ages etc makes it difficult for anyone here to offer any real help.
Perhaps you also need to start your own plan so that your children may join you here. Bringing your children here when you say you are destitute will be difficult for both you and them. Perhaps you should start by focusing on working and getting some funds together to make your situation that much easier.
I wish you well.
