Renewing non b visa n manila

[scubakev]

Hi can anyone tell if you can get a multiple non-b visa in manila.  I have been working in Thailand for the last year and already have a work permit but with al the visa problems I have got a new passport and got my last entry stamp reissued but now I need to get a new multiple no b visa and I plan to go on holiday to the Philippines and want to know what papers I need to take with me to get a new visa and do I need to do any thing with my work permit as it will run out when I am on holiday do I need to freeze it or just let it run out and renew it when I come back into Thailand.
