Hi Chiao,
In order to obtain a full FAA ATP + A330 endorsement without restriction you need to undertake the course on the left hand seat and perform circling app. very easy simulator. For all guys with ICAO Licenses i humbly recommend to get the FAA ATP without restrictions, even if you are usually flying as SIC in your countries. Most of the worldwide operators specially in Asia and Middle East request "clean" licenses.
I did a very short type based on the A320, was very easy. Contact Pan Am Academy. Highly recommended, fast and professionals.
Hope it helps.
