大家有申请成功过O-1 Visa吗？

最近听说了O-1 Visa（具体详见下面我复制粘贴的官网上简介）
想知道有没有小伙伴申请成功过该Visa，与H1B相比中签率如何？转绿卡的几率如何？谢谢！


O-1 Visa: Individuals with Extraordinary Ability or Achievement

[size=0.8125]Versión en español

[size=0.875]The O-1 nonimmigrant visa is for the individual who possesses extraordinary ability in the sciences, arts, education, business, or athletics, or who has a demonstrated record of extraordinary achievement in the motion picture or television industry and has been recognized nationally or internationally for those achievements.
The O nonimmigrant classification is commonly referred to as:

• O-1A: individuals with an extraordinary ability in the sciences, education, business, or athletics (not including the arts, motion pictures or television industry)
• O-1B: individuals with an extraordinary ability in the arts or extraordinary achievement in motion picture or television industry
• O-2: individuals who will accompany an O-1, artist or athlete, to assist in a specific event or performance.  For an O-1A, the O-2’s assistance must be an “integral part” of the O-1A’s activity. For an O-1B, the O-2’s assistance must be “essential” to the completion of the O-1B’s production. The O-2 worker has critical skills and experience with the O-1 that cannot be readily performed by a U.S. worker and which are essential to the successful performance of the O-1
• O-3: individuals who are the spouse or children of O-1’s and O-2’s
