Excuse my ignorance, but what is a 13A Visa? I intend to semi-retire to the Philippines.

My wife is Filipino but has a Dutch passport. We always get a yearly balikbayan (1 year stamp) when we go through passport control.

I have read somewhere that if we were to lodge US$ 10,000 (or more) we would not need a visa for a permanent stay. Could someone clarify my asumption.
