I am american, my fiance is filipina

we met in china a few years ago , and we will marry in phillippines on feb 10th, what is the best type to apply for her, i am here on business F always, and it should be no problem to get an invitation letter for her, tourist visa seems a bit unfair since she would need to leave every thirty days, isnt there a better way so that we can stay together, and not have to separate so much?
