My Deam Vacation

I carry a Philippine passport. What papers should I submit to the Mexican Embassy. I am planning to stay there only for three days and planning to return to USA for another six-months stay. I am already married to American Citizen but we don’t have yet all the necessary papers to submit toINS and I don’t want to overstay my six-months visa. My B2 six months visa will be expiring on January that’s why I am planning to exit USA and after my return we will complete all necessary requirements. It is possible to go to Mexico and return in USA? What papers do I have submit to get a visitor’s visa to Mexico? What travel agency is the best to get a cheap airline ticket, two way. My husband will accompany me and we don’t know where we will stay there for three days. Is there a three-day package tour? How much money should we bring for our trip to Mexico?How many hours from Houston, Texas to Mexico International Airport? What’s the best place to stay there without spending big money?
