Mine is up to date. We have a friend that just got one last Thursday. That's pretty up to date. If you keep up with it you will find its easy, plus my daughter is an attorney that does immigration. She says it much easier right now. But that may change after the election in USA.
Now a permanent resident visa is a totally different animal. My wife just got hers after two years. Visitor visas are not hard to get.
Do you and your wife live in the USA?
