The parallel EB-1A approach is highly widespread.

The O-1 typically solves short-term work authorization needs. Meanwhile, lots of workers start making an EB-1A green card application at the same time. This approach provides flexibility and avoids rushing the green card process later.

How long does it usually take?

Assuming that your profile already obviously qualifies as EB-1A, then the process can proceed faster:

• Preparation of petition: a couple of months.
• I-140 processing (premium available)
• Adjustment of status or consular processing

For applicants from countries without visa backlogs, the full process may take around 12–18 months.

When is additional profile building for EB-1A needed?

If legal counsel determines that you need to strengthen certain criteria, you should budget additional time. In many cases, that means adding 12–18 months before filing the EB-1A.

Some criteria are faster to build than others:

• Press coverage: can often be developed over 6 months with consistent exposure
• Awards: Certain competitive awards may be achievable within 3 months
• Judging roles: may depend on industry connections and timing
• Memberships: some require long-term tenure (for example, senior-level recognitions that require 10+ years in the field)

Due to the different rates of development of each of the criteria, the timelines are different. The earlier you align your O-1 strategy with a long-term green card plan, the smoother the transition tends to be.
