Where do I file for divorce if my husband lives in Colombia?

I want a divorce from my husband who is currently living in Colombia. I live in Philadelphia in our marital home. We lived here together for about 5 years before we split up and he moved back to where his family lives. I haven’t talked to him in over a year. Can I divorce him by filing here in Philly and if I can, how do I get the divorce papers to him if I don’t know exactly where he’s currently residing?
