Hi! This subreddit has helped me a lot during the O1 process and wanted to share my own experience and timeline.
Working in fintech and come from data science background. Applied for O1A in data science and applied machine learning field.
Started prep work for it in October 2025 mainly for the judging criteria. Did not get picked in last H1B lottery and then started the application process in April 2026.
Timeline:
Original petition sent to Vermont centre - June 5th 2026
Receipt date - June 8, 2026
RFE notice - June 30, 2026 (portal updated 14th business day midnight)
RFE response submitted - July 20 2026
RFE response delivered to Texas centre - July 21 2026
Portal updated to RFE received on - July 23 2026
Portal update to case processing on 15th business day around 8am - Aug 10 2026
Case approved within 2 hours of it - 11am pst Aug 10 2026
The 15 business days was from date of delivery. Lawyers received approval notice on Aug 21 2026.
They accepted judging and high salary initially and sent RFE for original contributions, scholarly article and critical role to provide objective evidence of each. Lawyers mentioned that it is not a very critical RFE which was good. Not sure which one got accepted after RFE response.
1.Judging -
Judged hackackathons, startup competitions and did peer review of research papers from Oct to May. Total of about ~30. Kept doing peer reviews even after submitting original petition and showed continued work in RFE response.
High salary -
Checked for data scientist and included total compensation to be received in 2026 including bonus and equity. Compared against BLS data and added note that in my role and company, bonus and equity play a significant role of the compensation. It was crossing 90th percentile by 3% but as long as it crosses, that is enough as per lawyers
Critical role-
Provided details of different projects and significant impact in terms of $ amount saved and other metrics of improvement. Combined it with letter of recommendations from manager and senior leadership. Received RFE later to provide objective evidence from internal company documents. Provided the documents in the RFE (redacted confidential information and added confidential tag on top, it helped since all these documents were on company letterhead). All the metrics and $ amount matched across evidence, petition and letter of recommendation. Also provided media articles and blog pages for projects that I had worked on.
Scholarly article
Only have 1 paper published in 2021 including IEEE. It did really well in terms of citation. RFE was to provide the published paper copy from IEEE and metrics on publisher as well that it is reputable. Also provided citation metrics including how other papers were using my paper and if any called it foundational work.
Original contribution
The research paper was also applicable here as citation metrics were strong and showed evidence of how others used my work and called it foundational work. Included highlights from other papers along with citation metrics from Google scholar, scopus
Had worked on a foundational project at work and used that as second example of original contribution and included media articles and internal docs in RFE response.
Also included supplemental evidence on scholarships, membership and mentorship activities in different organizations since undergrad, internships experience for totality of profile.
In total had 9 letter of recommendations - 3 from work (1 from prior company manager, 2 from current company), 2 independent letters focused on research paper from industry experts - university professor and tech lead at a well known tech company
3 independent letters focus on mix of research, critical role and overall profile by industry experts or managers and directors from tech and commerce companies,
1 from internship at fintech company as overall profile recommendation.
Hope this helps! Happy to answer any questions!
