That's what we're thinking after some light research - we'll probably dust off all our docs and organize the K3 ones this weekend.
Most are only valid for 6 months but I believe for immigration purposes it is valid for 2 years? I saw that in one of the forums here, I know lots of people have doubts about when to get it.
We're both living and working in Chile, so there's no way either of us make enough for the requirement. Thankfully my parents, despite retirement, are able to help.
That's a great question! I have no idea how long the wait it - where would I check that? I would assume short, from what I've seen on here there aren't a lot of people applying from Chile.
