Complete 2026 guide to apostilling New York diplomas and transcripts. Learn the mandatory 3-step process (notarization, county clerk certification, NY DOS apostille), fees ($10-15 total), and timelines for studying, working, or immigrating abroad.

What is a Diploma Apostille?

An apostille is an official certification issued by the New York Department of State that authenticates the signature of a notary public or authorized official on your educational document. For diplomas and transcripts, the apostille verifies that the notary or university registrar who signed/notarized the document is legitimate.

Important: The apostille does NOT verify the academic content (your GPA, degree, etc.). It only authenticates the signature/seal. This is essential for international use in Hague Convention countries for university admissions, work visas, or professional licensing.

The Required 3-Step NY Process

⚠️ Critical: Unlike California

New York requires a mandatory 3-step process. You cannot skip any step. California offers 3 alternative pathways, but NY requires all steps in sequence:

  1. Notarization (by university registrar or notary public)
  2. County Clerk Certification (authenticates the notary's signature)
  3. NY Department of State Apostille (final authentication)
1

Notarization

University registrar or NY notary public

2

County Clerk

Authenticates notary signature ($3-$5)

3

NY DOS Apostille

Final apostille certification ($10)

Notarization Options (Step 1)

You have two main options for getting your diploma or transcript notarized:

✅ Option A: University Registrar Notarization (Preferred)

Best option: Request a notarized diploma or transcript directly from your university registrar's office.

  • • University registrar is an authorized official
  • • Most NY universities offer this service
  • • Widely accepted internationally
  • • Typical fee: $10-30 per document
  • • Processing: 1-3 weeks

Examples: NYU, Columbia, Cornell, SUNY, CUNY all offer registrar notarization services.

Option B: Custodian Affidavit with NY Notary

If registrar notarization is unavailable, you can use a "custodian affidavit" where you sign a statement before a NY notary.

  • • You sign: "I certify this is a true copy of my diploma"
  • • Notary notarizes YOUR signature (not the diploma itself)
  • • Apostille authenticates the notary's seal
  • • ⚠️ Confirm destination country accepts this method
