hi salvadorean,
If you want 'professional' help with your question, could you post again but put "PMM please help" in the Subject. That person is (I think) a professional resource for answers on this list and has helped many people with the tricky questions about child custody etc.
For the type of immigration application, PMM might know which one you could apply under for your best chance.
Yes, there would be a fee for processing all of your immigration applications. I don't know the specific amounts, it is on the
Immigration website.
