Stop scrambling through Reddit threads about exhibit tabs. Upload your documents by category, and get a Bates-labeled, indexed, officer-ready PDF binder — assembled entirely inside your browser.
USCIS officers expect a professionally organized evidence binder at your I-485 interview. Nobody tells you this — until you're searching Reddit at midnight, six weeks before your appointment.
Hours in Word or Acrobat manually numbering pages, creating tab separators, building a table of contents — only to get the Bates stamp format wrong.
No single guide agrees on exhibit order, what counts as "Exhibit A," or how many copies to bring.
Generic PDF tools (Acrobat, DeftPDF) have no idea what an I-485 interview requires — no exhibit categories, no cover letter, no affidavit templates.
No installs, no account, no learning curve. Everything runs in your browser.
Seven pre-built marriage-evidence exhibit categories. Drag your PDFs, photos, and scans into the right bucket. Reorder or remove any file before assembling.
A short form collects petitioner/beneficiary names, receipt number, and sponsor income. This populates your cover letter and I-864 affidavit template automatically.
One click assembles the binder in your browser — Bates numbers, tab separators, index page, cover letter. Pay with Stripe, then download the finished PDF. Done.
Built specifically for the I-130/I-485 marriage AOS interview. Every exhibit your officer expects — nothing more, nothing less.
US passport, birth cert, or naturalization certificate
Foreign passport, visa, I-94, prior immigration docs
Marriage cert, wedding invitation, ceremony photos
Joint bank statements, joint tax returns, joint credit cards
Lease/mortgage with both names, utility bills, insurance
Travel records, call logs, chats, family affidavits
Tax returns, W-2s, pay stubs, employer verification letter
One PDF. Everything an officer expects when they open your binder at the interview desk.
Every page stamped with sequential case-specific numbers (e.g., SMITH-000001). The format officers use to reference documents during the interview.
Labeled divider page before each exhibit section (Exhibit A, B, C…) so the officer can flip directly to any category.
Auto-generated front page listing every exhibit with its title and the Bates number where it starts.
Pre-filled with your names, case number, and a list of the enclosed exhibits. Print and attach to the front of your printed binder.
Pre-populated with sponsor name, address, and income figures you entered. Fill in, sign, and include in Exhibit G.
One file, ready to print at home or at a copy shop. No software needed after download.
We know you're uploading passports, tax returns, and marriage certificates. That's why BinderKit is built to process everything locally, in your browser.
Your documents are read and processed using browser-native JavaScript APIs. Nothing is sent to our servers — or anyone else's. Open DevTools → Network and watch: zero uploads.
When you close the tab, your documents are gone. We don't have them, we can't see them, we can't leak them.
We're not asking you to trust a privacy policy. Open DevTools before you upload and watch the Network tab yourself. The evidence is right there.
You already paid $1,760+ in USCIS filing fees. A $40 one-time tool to walk into your interview organized is a rounding error.
