I know that the tourist visa limit is 30 days, and that I intend to get visa extensions to allow me to stay 3 months. It is however $700 cheaper to buy a ticket with the specific arrival dates and departure dates I intend (for 3 months stay) , as opposed to having to purchase a ticket with a departure date within 30 dates of my arrival, and then cancelling this flight and repurchasing a flight for the actual return date. It seems like it is possible to purchase a ticket to the Philippines with an arrival date and return date more than 30 days apart, but I dont want this to be rejected by the Philippines immigration on my arrival.
