usa – 11 years Overstayed in the Philippines

My son got overstayed in the Philippines for 11 yrs and I want to bring him back here in US but I don’t know how much the fines by now. I don’t want to go to BI if I don’t have enough money to pay for the fines. Is anyone has an idea how much the fines cost? I’ll appreciate who will answer this.. thank you.

Also is it ok to travel in to Philippines now? What are the requirements to travel?
