It's the airline, because if you get deported, sending you back comes out of their pocket. So the best way to handle it is to buy a ticket to Guam a day before on an American carrier, specifically United. Then cancel it pretty much right away. They won't look up the reservation number anyway, so on paper it shows you have an onward ticket.

I had my onward ticket checked and entered into a system, but it passed. This was at LAX.

It doesn't have to go back to where you came from; any onward flight will do. Flights to Taiwan or Hong Kong are about 4k pesos.

Yes. Immigration doesn't care; it's the airline that checks. Why not just use the fake onward ticket that's been talked about to death on this sub?

I've never been asked by Philippine customs, but the airline always asked before letting me board. Check out OnwardTicket. It's a temporary ticket, and it was $16.50 the last time I used it.

Well, in my case, my wife is Filipino and is now an American citizen. Even so, she still gets the 1-year visa, and so do I. We didn't even know that. We only noticed after arriving that we had the one stamp. Apparently we were supposed to have our marriage certificate, but nope. We'd also filled out the E-pass thing but never had to show it.
