Someone mentioned that you're from a high fraud country, that's completely their opinion and that of the current administration as at that time to justify what was to come. Don't forget to add that muslims were killing christian rhetoric as well. There's no proven fact to justify any of these claims.
The reason for the delay is directly associated to the same claims above and as indicated in Proclamation 10998 announced in November, its purpose was to update 10949 and it created PM-602-0194: Hold and Review of USCIS Benefit Applications Filed by Aliens from Additional High-Risk Countries, which took effect on January 1, 2026.
Bottom line for Countries on the list:
Applications are NOT frozen, but they face heavier scrutiny and longer processing times across most USCIS benefit types.
What stays the same:
People from the listed countries can still file USCIS applications and petitions.
Biometrics, interviews, and background checks continue.
Approvals are legally possible.
There is no automatic denial just because the applicant is from those affected countries.
What changes:
Cases are routed for enhanced vetting.
More delays than usual.
Higher likelihood of RFEs, additional documentation requests, and supervisory review.
Some previously approved cases may be re-reviewed, though less aggressively than for full-restriction countries.
The 10949 clause of who entered the United States on or after January 20, 2021 is irrelevant and to me a bambozzle. As long as your country is listed in PM-602-0194, all immigration cases are on hold, and it may be for a long time or up to the next administration.
Your N400 was canceled because I751 will not be approved and put on hold. Your interviews must have been scheduled before June, 2025. Anyway, I'll advise you to pray and be ready for a very long wait, no rush, don't reach out to USCIS for updates anymore, stay out of troubles, away from violence or any incident that may fault you and/or involve the cops. You're currently trying to outlast this administration policy or until they reverse course.
