What documents do I need after an ITA — and is 60 days really enough?

After an invitation you have 60 days to submit a complete application: passport, language results, ECA, job reference letters, police certificates from countries where you've lived, an immigration medical exam, proof of funds (if required), and photos. Sixty days is enough only if you prepare early — police certificates from some countries take months. Smart applicants gather documents while still in the pool, so the ITA becomes an upload exercise, not a scramble.
