How long do you have to live in Florida to get an uncontested divorce?

My husband is a dual citizen of Egypt and U.S. He left me and my kids to go back to Egypt several years ago. There is nothing left of what we had and we don’t own a home together anymore. I don’t expect him to come back at this point and I just want a divorce. How do I get an uncontested divorce from him if he no longer lives here in Miami? Do I still have to serve him with papers if I’m not asking for any property? Also, is there any way I can get him to pay child support for our 3 kids? He sent some money when he first left but hasn’t sent anything for the kids in over a year now.
