Harbor

Harbor helps immigrants in the United States follow their USCIS case — in their own language. Add your receipt number and Harbor checks your official USCIS case status for you, showing the original English status alongside a clear explanation in your language. When the status changes, you get a push notification right away — so you never have to keep refreshing the government website. WHAT YOU CAN DO • Track USCIS cases — your official status, a plain-language explanation, and a timeline of every change. • Get notified — a push the moment your case updates. Quiet by default; you choose what to be notified about. • Follow the Visa Bulletin — track your category and priority date, and get alerted when dates advance or retrogress. • Compare processing times — current USCIS processing times for your form and office. • Prepare for citizenship — study and quiz yourself on the U.S. civics test in your language. BUILT TO RESPECT YOU • Your language first — Simplified Chinese, Traditional Chinese, English, Spanish, Vietnamese, and Korean. • Private by design — your data is encrypted, never sold or shared, and you can permanently delete it anytime. • Clean and quiet — a focused tool, no ads, no clutter. Harbor is not a law firm and does not provide legal advice. It is not affiliated with, or endorsed by, USCIS or any U.S. government agency. All data comes from official, public sources and may be delayed. Always rely on official USCIS notices for your case.
