O-1A has three filing-mandatory requirements that are different from employment-based green cards. Check these before starting:
O-1A cannot be self-petitioned. You need either a US employer willing to file Form I-129 on your behalf, or a US immigration attorney or accredited representative acting as your US agent. Athletes and performers often use US agents; researchers typically use employer-institutions. The Tier 1 assessment analyses your specific situation and recommends which route fits.
USCIS requires a written advisory opinion from a peer group, labour organisation, or management organisation relevant to your field (8 CFR §214.2(o)(5)). Examples: IEEE for engineers, AMA for physicians, ACM for computer scientists, sport-specific governing bodies for athletes. Tier 2 and Tier 3 include a draft peer consultation letter tailored to your named peer organisation.
USCIS requires a written contract between you and the US petitioner, or a summary of the terms of a verbal agreement. This establishes the nature of the work, duration, compensation, and type of engagement. The Tier 3 Filing Strategy Brief includes the practical I-129 filing checklist with all required supporting documents.
Planning permanent residence? Many O-1A holders later transition to EB-1A (Extraordinary Ability Green Card) or EB-2 NIW (National Interest Waiver). Orabo has tools for both pathways.
