For a temporary visitor or tourist visa, the general minimum requirements are:
- Passport/Travel Document Valid for at least six (6) months beyond the intended period of stay in the Philippines;
- Duly Accomplished Visa application form;
- Proof of bona fide status as tourist or businessman;
- Confirmed tickets for return or onward journey to the next port of destination;
But again, this can vary depending on the country of your passport, so make sure to check with your embassy in Manila.
