Why ImmiSupport Filing Agents Stand Out?

📍 Nationwide Agent Network
From California to New York, we’ve built a network of trained agents ready to deliver, file, and confirm no matter where the paperwork is headed.

📑 Trained in Immigration-Specific Handling
Our agents understand how USCIS, EOIR, and federal filings work — so they know not to bend forms, mislabel packages, or skip signature checks.

📦 Priority & Overnight Options
Need it there tomorrow morning? We’ve got options. We work with USPS, FedEx, UPS, and private couriers to meet tight deadlines.

🔍 Transparent Tracking & Proof
Every package comes with a digital paper trail — scans, receipts, timestamps, and delivery confirmations you can share with clients or attach to your records.

🔒 Secure & Confidential Delivery
We protect sensitive documents from the moment they leave your office to the moment they’re signed for. HIPAA-trained, always.

🧩 Seamless Integration With Your Team
Whether you work with Dropbox, Docketwise, or Clio — we coordinate directly with your legal assistants or paralegals to ensure smooth fulfillment.


What Attorneys Are Asking About Filing Agents?

1. Why do I need a filing agent if I already mail things myself?
Because time is money. Filing agents ensure that what you send is packaged, documented, and delivered correctly — on deadline and without errors that could delay or reject your case.

2. Can you handle same-day filings or urgent submissions?
Yes. We can expedite filings, arrange local drop-offs, and provide real-time tracking for urgent filings. Just say the word — we move fast.

3. What if the filing requires local presence, like a court clerk hand-off?
We’ve got agents in key metro areas trained to physically deliver documents to government agencies and courts where e-filing isn’t available or accepted.

4. Will I get proof of delivery?
Always. We provide scanned receipts, delivery confirmations, and any return labels or notes, all documented for your records and compliance.

5. How do you ensure filing accuracy?
Our agents work off detailed checklists. We double-check the basics (signatures, checks, forms) and follow USCIS or court-specific mailing instructions for every submission.

6. How are you different from using FedEx or a virtual mailbox?
We’re not just a delivery service we’re a legal document handler. We know what needs to be filed, how it needs to look, and what happens if it isn’t right. We combine the speed of a courier with the precision of a paralegal.
