Study abroad - top universities.com

Sir,

I noticed that CAClubindia is affliated as a media partner in Top univeristies.com.

I have a few questions relating to studying abroad. I want to pursue PhD in Finance in US after my CA.

1) Is CA recognised in US universities?

2) Which are the best universities to apply to?

3) What other tests and procedures should i undertaken before applying?

Any details on the above topic will be helpful.
