What is an Apostille?

Many people in San Mateo mix up an apostille with a standard notary stamp. The two serve entirely different purposes. A notarization merely authenticates that the person who signed the document is who they claim to be. It carries no international legal weight. An apostille, by contrast, is a standardized Hague certificate recognized by all Hague Convention member countries certifying that the document's seals and signatures are legitimate.

An apostille on your Diploma is required any time an overseas government, employer, or institution asks you to provide certified US public documents. Common situations include immigration proceedings, overseas job offers, foreign university admissions, and cross-border legal matters. Because San Mateo is in California, the apostille for your Diploma must come from the California Secretary of State in Sacramento, not from any county or municipal office.

The Hague Apostille Convention now counts more than 120 countries — spanning all EU member states, most of Latin America, and key expat destinations worldwide. When you need documents for any form of immigration, employment, or international study, an apostille on your Diploma is almost certainly a requirement. Our courier service handles California-based orders for all 124 member countries.

State vs. Federal Apostille: Which Applies to Your Diploma?

Figuring out if your Diploma falls under state or federal jurisdiction is generally simple. Ask yourself: who issued this document? Documents like Diplomas issued by California government agencies go to the California Secretary of State in Sacramento. FBI Background Checks and federal agency records are processed by the US Department of State in Washington D.C.

A question we often hear is whether there is any way to track their document during the apostille process. If you mail your document yourself, tracking ends at postal delivery confirmation. Through our service, status notifications come at every step: intake, delivery to the California Secretary of State in Sacramento, apostille issuance, and return FedEx tracking to San Mateo.

The most critical thing to know about the apostille process for your document is determining which government authority handles your specific document type. In the US, there are two completely separate authentication tracks: state-level and federal. Documents issued by California, including Diplomas go to the California Secretary of State in Sacramento. Federally issued records, such as FBI Background Checks, must go to the US Department of State in Washington D.C..

Why a Local Notary in San Mateo Cannot Apostille Your Document

You may have seen document preparation companies in CA claiming to offer apostilles. These businesses are intermediaries — they cannot issue apostilles directly. Their role is submit your documents to the correct authority on your behalf. The Global Apostille Network does exactly this but with a dedicated runner network at both state and federal offices.

If you are working under a tight deadline, relying on postal mail to the California Secretary of State is risky. A courier-assisted submission reduces turnaround from weeks to days. Our team serves all cities in California with complete end-to-end shipment tracking on every submission.

Beyond notaries, county clerks, municipal offices, and city government offices in CA also cannot issue apostilles. Even visiting the San Mateo city hall, county courthouse, or register of deeds will not produce an apostille. The sole authority in California that can attach the Hague certificate for state documents is the California Secretary of State.

The Correct Authority: California Secretary of State in Sacramento

Before submitting to the California Secretary of State, specific conditions apply. Your Diploma must bear an authentic original seal. Photocopies are not accepted. If your Diploma came from a local government office, it may need to be re-certified at the state level before submission. We checks every document before submission to ensure it meets the California Secretary of State's requirements.

A common question from San Mateo clients is whether they can track their document during the apostille process. With direct mail submission, tracking ends at postal delivery confirmation. With our courier service, you receive real-time updates: intake confirmation, delivery to the California Secretary of State in Sacramento, apostille issuance, and return FedEx shipment tracking to San Mateo.

When apostilling a Diploma from California, the correct office is the California Secretary of State. Only the California Secretary of State is authorized to attach Hague Apostille certificates on records from California government agencies. The California Secretary of State holds the official seals of California government officials and is therefore the only entity capable of certifying their authenticity.

Step-by-Step: Getting Your Diploma Apostilled from San Mateo

Before anything else, you must have your Diploma in the right form. For state records, you need an official certified copy — not a photocopy. In the case of your document, an original official seal is required — uncertified copies are not accepted by the California Secretary of State.

The complete timeline for getting your document apostilled from San Mateo includes: obtaining the right version of your document, pre-apostille notarization if needed, courier transit from San Mateo to the California Secretary of State in Sacramento, government processing time, and return shipment to San Mateo. Without an expedited courier, the entire process runs 4 to 8 weeks. With a physical courier, turnaround shrinks to 2 to 5 business days for the government processing portion.

Once the apostille is issued, it is legally valid for submission to any Hague Convention member country. For some countries, you will also need a certified translation. Most non-English-speaking Hague member countries require a sworn translation. We offer comprehensive packages that include both apostille and translation.

How Long Does a Diploma Apostille Take from San Mateo?

For time-sensitive requests — such as a visa appointment, consulate date, or employment start — starting early is essential. Budget 2 to 4 weeks lead time for postal submission and at least 5 to 7 business days for courier service. Rush options may be available depending on the California Secretary of State's current capacity.

Knowing where your Diploma is is a key advantage of using our courier service. We provide real-time tracking at every milestone: initial pickup, receipt by our team, submission to the California Secretary of State in Sacramento, completion confirmation, and outbound FedEx tracking back to San Mateo. This end-to-end tracking is not possible with direct mail.

The US Department of State has its own processing timeline for FBI Background Checks and other federal records. Standard mail-in processing to the Office of Authentications can take 6 to 11 weeks due to the national volume of federal authentication requests. A DC-based courier can complete the federal apostille in 2 to 4 business days by physically submitting at the federal office.

What to Include with Your Diploma Apostille Submission

When apostilling more than one document, each document requires its own apostille certificate and its own state fee of $20. One apostille cannot cover multiple documents. Our service coordinates bulk submissions and ensures every document is individually apostilled and returned.

Once you have your document back, inspect the apostille to confirm that the certificate is properly attached, the information on the apostille matches your document, and there are no visible errors. If you notice any discrepancies, notify the California Secretary of State in Sacramento promptly. Errors in the apostille are rare but should be caught before you submit to the foreign authority.

The California Secretary of State in Sacramento will only process original or properly certified versions. Uncertified photocopies or digital prints are not accepted. If your original Diploma was lost, a new certified copy must be obtained from the source before submitting for an apostille. For documents from California agencies, the issuing state or county office can provide certified copies.

Common Apostille Mistakes San Mateo Residents Make

Incorrect payment is an easily avoidable mistake. The California Secretary of State in Sacramento charges a specific state fee per apostille document. Underpaying or overpaying means the California Secretary of State will return your document unprocessed. Our service handles the fee payment directly so you are never delayed by a payment issue.

An often-missed issue is submitting a document that has been altered. If your Diploma shows any signs of modification or handwritten additions, it will likely be turned away. If changes are needed, must be made officially at the issuing agency. Our intake review catches this type of problem before submission happens, saving you time and avoiding first-attempt rejection.

The number one mistake is routing your Diploma to the incorrect office. San Mateo residents sometimes send state documents like Diplomas to the US Department of State in DC. Either way, the documents come back with a rejection notice. This adds 2 to 4 weeks — the round-trip postal time to the wrong office — before you are even back to square one.

Shipping Your Diploma from San Mateo — What to Know

Return shipping is included in our flat-rate service fee. Once the government office issues the apostille, we ships your Diploma back to San Mateo via FedEx with priority shipping with a tracking number sent to your email. Most return shipments arrive within 1 to 2 business days. Rush return shipping is an option for urgent situations.

Once we receive your Diploma at our hub, our intake team checks it the same or next business day. The intake check verifies: document type and certification status, whether the official seals and signatures are present and readable, whether any pre-apostille notarization is required, and whether the document is within any recency window required by the destination. If any issues are found, we reach out to you within one business day before submitting to the California Secretary of State.

The most important rule when sending original documents like your Diploma is never use standard mail without tracking and insurance. Sending documents without tracking or insurance creates unnecessary risk: if a document is lost in transit, there is no way to locate or recover it. FedEx Priority and UPS provide end-to-end tracking with insurance. For originals that cannot be easily replaced, the peace of mind is worth the extra cost.

After the Apostille: Using Your Diploma Abroad

When you receive your returned apostilled Diploma, inspect the certificate carefully before sending it to the foreign authority. Verify that: the certificate is properly affixed, the information on the certificate matches your document, and the California Secretary of State's seal and signature are on the certificate. Problems with the certificate itself are uncommon but are best identified before your consulate appointment.

One detail worth understanding is that the Hague certificate certifies authenticity, not content accuracy. If there is an error in your Diploma itself — a misspelled name, wrong date, or factual inaccuracy — the apostille does not fix it. A consulate can still refuse an apostilled Diploma if there are errors in the document itself. Fixing errors must be addressed at the source agency — not at the apostille stage.

After receiving your apostilled Diploma, you are ready to submit it to the foreign consulate, embassy, immigration authority, or employer. Different authorities have different submission procedures: some require in-person delivery, others accept documents by mail or online portal. Confirm the specific submission process with the receiving authority in advance to ensure your submission is accepted.
