What Is a Diploma Apostille?
The Hague Apostille Convention replaced a previously complex chain of certifications that was standard before the Hague system. Under the old system, getting an American document accepted overseas required notarization, state-level certification, federal certification, and then embassy legalization. The Convention simplified this into a single certificate issued by one designated authority. For Diplomas issued in Oklahoma, that authority is the Oklahoma Secretary of State in Oklahoma City.
Diplomas are among the most frequently apostilled documents in the United States. The reason Diplomas come up in many international processes including visa applications, residency permits, citizenship documentation, employment verification, and foreign legal proceedings. For residents of Oklahoma, the apostille for a Diploma must come from the Oklahoma Secretary of State.
An apostille is a standardized Hague certification formalized by the 1961 Hague Apostille Convention. Unlike standard document certification, an apostille is accepted by all 124 Hague member countries — meaning your Diploma is valid for submission to overseas institutions without further legalization. If you are in Oklahoma, Oklahoma, obtaining this certification goes through the Oklahoma Secretary of State in Oklahoma City.
Oklahoma: State vs Federal Authority
For state-issued Diplomas, the apostille must come from the Oklahoma Secretary of State's office. Typically, the document needs to be in certified form with an authentic seal. The Oklahoma Secretary of State verifies the document's origin and seal and attaches the apostille typically in 1 to 3 weeks.
A frequent and expensive error is routing your Diploma to the incorrect government authority. For example, if you mail a Diploma issued in Oklahoma to the US Department of State in DC, it will be rejected and returned. Similarly, mailing a federal document to the Oklahoma Secretary of State in Oklahoma City results in the same rejection. Either way, the round-trip postal time adds 2 to 4 weeks to your timeline.
If you have a deadline, expedited apostille service is offered by our courier service. The Oklahoma Secretary of State in Oklahoma City provide same-day service for in-person deliveries. Our courier takes advantage of in-person processing by walking documents in, which is typically the only way to access same-day or next-day processing.
Why Local Offices Cannot Help
Many residents of Oklahoma mistakenly believe they can obtain Hague legalization at a local notary office in Oklahoma. This is incorrect. A notary public can only witness signatures and verify identity. They are not permitted to attach an apostille certificate — only the Oklahoma Secretary of State can do this.
Something else to consider is that the receiving country will verify that the apostille came from the correct authority. If your Diploma is apostilled by the wrong authority, your documents will be rejected at the destination. This may trigger a visa denial even if everything else in your application is correct.
Beyond notaries, county clerks, municipal offices, and city government offices are equally unable to apostille documents. Even a trip to any local Oklahoma government office would not produce a Hague certificate. The sole authority in Oklahoma authorized to issue apostilles for state documents is the Oklahoma Secretary of State in Oklahoma City.
The Oklahoma Apostille Authority
There is sometimes a step before apostille submission: some documents require prior notarization. Diplomas, powers of attorney, and affidavits typically require notarization as a first step. Our team advises you on any pre-apostille requirements before submitting to the Oklahoma Secretary of State so there are no delays from missing prerequisites.
For Diplomas issued in Oklahoma, the correct office is the Oklahoma Secretary of State in Oklahoma City. This is the only office in Oklahoma authorized to grant Hague Apostille certificates on Oklahoma-issued public documents. The Oklahoma Secretary of State is authorized to verify the seals and signatures of all Oklahoma public officials and is consequently the only authorized source for apostilles on Oklahoma-issued records.
Once your document arrives at the Oklahoma Secretary of State, a state official verifies the seals and signatures and checks that signatures are from known, authorized officials. Once verified, the apostille is affixed as a separate certificate appended to your document. The completed document is then returned by mail. Our courier retrieves it and ships it back to Oklahoma.

How Long Does a Diploma Apostille Take in Oklahoma?

The Oklahoma Secretary of State in Oklahoma City offer same-day service for walk-in submissions. Our runner uses this option wherever available to get Oklahoma clients their apostilles within a business week.
The US Department of State operates on a separate schedule for federal documents. Standard mail-in processing to DC for federal apostilles can take 8 to 12 weeks because of the volume of requests from all 50 states. A physical courier in Washington D.C. gets the federal authentication done in 2 to 4 business days by physically submitting at the federal office.
Knowing where your Diploma is is one of the most valued aspects of a physical courier over postal mail. We provide status updates at every milestone: pickup from your Oklahoma address, receipt by our team, delivery to the government office, completion confirmation, and dispatch of the return shipment to Oklahoma.

What to Include With Your Submission
Before sending your document to the Oklahoma Secretary of State, ensure you have: your original Diploma or an official certified copy, notarization if required for your document type, the Oklahoma Secretary of State's request form if applicable, correct fee payment for the state apostille, and a prepaid FedEx or USPS return. Leaving out any item will delay your apostille.
Some Oklahoma residents ask whether a cover letter is needed with their apostille submission. For direct submissions to the Oklahoma Secretary of State, including a short cover page is advisable stating your name, document type, document count, and return address. The Oklahoma Secretary of State handles many submissions daily and a simple cover sheet helps the office handle your request correctly and quickly.
Payment for the state fee must be included. Accepted payment methods vary by state but typically include personal check, money order, or credit card for online portals. We includes fee payment in our all-in-one courier package so the submission is never rejected for payment reasons.
Common Apostille Mistakes to Avoid
Failing to provide a prepaid return label is a simple but common mistake. The Oklahoma Secretary of State in Oklahoma City does not automatically return documents. Without a prepaid return envelope, your completed apostille could wait weeks to reach you. We handle return shipping as part of our flat-rate fee — no separate arrangements needed.
The most common and costly apostille mistake is sending your document to the wrong government authority. People in Oklahoma sometimes mail state documents like Diplomas to the US Department of State in DC. In both cases, the documents come back with a rejection notice. This mistake costs weeks — the time lost in transit to and from the wrong authority — before you are even back to square one.
Sending original documents through the US Postal Service without a tracking number is a significant risk. Documents sent by uninsured mail can be lost, delayed, or damaged. Vital records and FBI Background Checks are sometimes time-consuming and costly to replace. We use FedEx with full insurance and tracking for complete end-to-end protection.

Order NowFrequently Asked Questions — Diploma Apostille in Oklahoma
Does my Diploma need to be notarized before apostilling in Oklahoma?
Yes. Most Secretary of State offices — including the Oklahoma Secretary of State in Oklahoma City — require that Diplomas be notarized or officially certified by the issuing institution before an apostille can be attached. We coordinate the full process: notarization, submission to the Oklahoma Secretary of State, and return of the completed apostille.
Which state handles the apostille if I now live in Oklahoma but attended school elsewhere?
The apostille must come from the state where the issuing institution is located — not the state where you currently live. If your Diploma was issued by a Oklahoma institution, the Oklahoma Secretary of State in Oklahoma City is the correct office. If you attended school in another state, that state's Secretary of State handles the apostille.
How do I get a certified copy of my Diploma suitable for apostilling?
Contact the institution that issued your Diploma — typically the registrar, alumni office, or records department — and request an officially certified copy bearing an original seal or signature. This certified copy, not a photocopy, is what the Oklahoma Secretary of State in Oklahoma City will accept. We can advise on institution-specific requirements when you place your order.
Will my apostilled Diploma from Oklahoma be accepted in countries that require specific formats?
Countries like Germany and the UAE have specific requirements for educational documents beyond the apostille — including certified translations and sometimes additional attestation. The apostille from the Oklahoma Secretary of State in Oklahoma City satisfies the Hague authentication requirement, but you may also need a sworn translation and, in some cases, attestation by the destination country's embassy. We offer full packages that cover apostille plus translation.
