Add your filing date and case type to estimate when a decision window might open. Processing times at USCIS vary more than almost any other federal agency.
A scheduling range built from historical form-level averages.
Each case type carries a typical processing range, expressed in months, built from historical patterns rather than any single office's current queue. The calculator adds that range to your filing date to produce an earliest and latest likely decision window. Take the tool's own default: an N-400 filed January 15, 2026 carries a 6-to-12-month range, which lands the decision window between July 15, 2026 and January 15, 2027. Switch the case type to I-130 with the same filing date and the window stretches to September 15, 2026 through March 15, 2027, because family petitions historically run both longer and less predictably than naturalization cases.
| Case type | Typical range |
|---|---|
| I-130, spouse of U.S. citizen | 8 to 14 months |
| I-485, adjustment of status | 8 to 14 months |
| N-400, naturalization | 6 to 12 months |
| K-1, fiancé(e) visa | 10 to 16 months |
| I-765, work permit (EAD) | 3 to 8 months |
| H-1B, specialty worker | 2 to 6 months |

Because a single predicted date would overstate how precise these estimates are. USCIS processing times vary by service center, current workload, and case complexity, so a range communicates that uncertainty honestly instead of hiding it behind false precision.
I-130 and I-485 carry the widest built-in range in this tool, 8 to 14 months, which reflects how much family-based petitions and adjustment-of-status cases vary between field offices. N-400 naturalization runs a tighter 6 to 12 months.
Certain forms, including many H-1B petitions, qualify for premium processing at an added government fee, which guarantees action within a set number of business days. Most other forms only qualify for an expedite, and only for a specific reason such as severe financial loss, humanitarian urgency, or a USCIS error.
USCIS publishes current processing times by form and field office at its case-processing-times tool. That page updates more frequently than any static range, including this one, so treat it as the tie-breaker whenever the two disagree.
No, it is a scheduling estimate built from historical ranges, not a legal opinion. Consult an immigration attorney about your specific filing and timeline concerns.
