to catch celebi you need to............ Take part in a Celebi Giveaway. I heard that in the US the Gamestop Stores might be holding a giveaway in May of 2010. I don't know if it is true or not.

Currently, there is no way to get a official Celebi outside of Japan. However it may be possible to capture Celebi in future events.
well you cant catch it in Pokemon white you have to get it in Pokemon heart gold or soul silver using an event IF YOU ONLY WANT CELEBI WELL YOU CAN ALSO GET ZORUA IN CASTELIA CITY WITH CELEBI SO ID DO THAT ONCE YOU GET CELEBI
There are only a few you can catch but the rest you have to get from trades with other games.
Either trade or do that event
