Expert Recognition:

6 peer reviews completed for prestigious journals
4 expert recommendation letters. One expert has stated that:

“Therefore, [Client]’s results allow scientists to detect even the smallest deviations that indicate new physical phenomena beyond existing theories.”

Result

Thanks to our comprehensive petition strategy and meticulous documentation, USCIS recognized the extraordinary nature of these achievements and approved the petition in an exceptional timeline. This outcome reflects not only the exceptional qualifications of our beneficiary but also our firm’s expertise in presenting compelling evidence that satisfies the demanding EB-1A standard on the first submission.
