There is no 12 month visa.
Be very careful about exactly what you think you'll be getting with a 1 year multiple entry visa......it may not actually be what you imagine or what you actually need.
As always, I stand to be corrected, but here's my understanding....a multiple entry visa allows you to enter any number of times within it's validity BUT your visa time expires every time you leave. Next time you enter you'll be started again with 59days....and don't forget you'll need to have an onward ticket each time you enter.
You may apply for visa extensions to stay for longer than the initial visa free period.
You may also secure the new 6 month tourist visa.
However...... even with this it will still expire when you leave the country irrespective of how long the visa still has to run. Means starting agin from scratch on re-entry.
If you have a definite need to 'come and go' multiple times to Philippines then a Mutliple entry visa is perfect.
If you want to stay then save some money and inconvenience and follow the suggestion posted by fred above.
