Hi,
All documents need to be colored copy. Black and white with a certified true copy may face rejection.
For your passport, you are supposed to scan both old and new passport from page 1 to the last page. Even if there are no stamps on certain pages, it must be scanned as well. In addition, all 4 corners of the passport must be shown. The best way to get this done is to go to a photocopy machine, put a blank piece of paper on top of your passport and scan it. Regardless whether a not you travel to the country, as long as it is in the passport, all must be scanned. In short, scan every page of your passport.
