Both are extraordinary-ability routes. O-1A is temporary work; EB-1A is a green-card petition. Evidence bars are related but not identical.
| O-1A | EB-1A | |
|---|---|---|
| Typical intent | Temporary US work | Permanent residence |
| Petition style | Usually US employer/agent petitioner | Self-petition common |
| Evidence intensity | High — multi-criterion | Very high — final merits |
| Employer dependence | High for petitioning | Low if self-petitioning |
