Which authentication process do you need?

Step 1 of 5

What is the destination country for your documents?

What your destination country requires: the one deciding rule

International document authentication is governed by a single factor that eliminates all ambiguity. The 1961 Hague Convention divided the world into two clear categories — and your destination's membership status dictates exactly which process you must use. You cannot choose a preferred option:

Is the destination country a Hague Convention member?

✅ YES → Apostille from one designated authority     ❌ NO → Full consular legalization chain

Spain, Mexico, Colombia, Argentina, the US, the UK, and 125+ other countries are Hague members — apostille applies. China, Saudi Arabia, Pakistan, Vietnam and other non-Hague countries require the full multi-step consular chain. We identify the exact process and authority for your specific case:

  1. Confirm destination country's Hague membership status
  2. Identify the correct competent authority — federal or state apostille, or which embassy for legalization
  3. Prepare and submit documents with certified translation where required

We handle the complete process in one coordinated service — apostille or full legalization chain, with certified translation included in Standard and Rush packages.

Who needs this service?

🇪🇸 Spain visa & residency applicants

Spain is a Hague Convention member — apostille is the required process for all documents submitted to Spanish consulates and immigration authorities (Extranjería). We apostille your documents and coordinate certified Spanish translation in one service.

🇨🇳 Professionals working in non-Hague countries

China, Saudi Arabia, Qatar, and other non-Hague countries do not recognize the Hague Apostille framework. If you are relocating for work or business, your documents require the full consular legalization chain — notarization, state, federal, and embassy authentication.

🌍 Applicants unsure which process they need

The Hague membership list changes — Canada joined in 2024, UAE joined in 2021. If you are not certain whether your destination country is Hague-eligible, we review your specific case and confirm the exact process and authority before you commit to anything.

Required documents

Original public document Issuing authority (Civil Registry, university, court, FBI, etc.) Variable by document type Original with wet-ink signature and official seal. Photocopies are rejected by both apostille and legalization authorities.
Apostille certificate (Hague countries) US Dept. of State (federal) or Secretary of State (state) Standard 4–8 weeks / Expedited 5–7 business days Sufficient for 125+ Hague member countries. Federal documents (FBI) → US State Dept. only.
Notarization (legalization chain — step 1) Local notary public 1–2 business days First step in the consular legalization chain for non-Hague countries. Some documents start from state level if already notarized.
State authentication (legalization chain — step 2) Secretary of State or state equivalent 3–10 business days Verifies the notary's credentials. Required before federal authentication.
Federal authentication (legalization chain — step 3) US Department of State — Authentications 5–15 business days Verifies the state official's signature. Required before embassy legalization.
Embassy / consulate legalization (step 4) Embassy of the destination country 1–4 weeks (varies by embassy) Final stamp of the destination country's embassy. Fees and turnaround vary significantly by country.

Common rejection reasons — and how we prevent them

Most rejections happen because the wrong process was used or the wrong authority received the documents. Our pre-submission review catches every issue before it costs you time and money:

  • Using apostille for a non-Hague destination — An apostille on documents destined for China, Saudi Arabia, or Pakistan is completely invalid. The receiving authority will reject it outright. We confirm Hague membership before processing anything.
  • Using legalization when apostille suffices — Going through a full 4-step consular chain when a simple apostille would work wastes 4–12 weeks and $300–$500 in fees. We identify the correct and most efficient process for your specific destination.
  • Wrong apostille authority for US federal documents — FBI Identity History Summaries and other federal documents must be apostilled by the US Department of State. Sending them to a state Secretary of State causes rejection. State offices have no authority over federal records.
  • Photocopy submitted instead of original — Both apostille authorities and embassy legalization offices require originals or certified copies issued directly by the originating institution. Notarized photocopies are not equivalent.
  • Missing intermediate steps in the legalization chain — Sending a document directly to the embassy without state and federal authentication first is a complete rejection. We manage every step of the chain in sequence.
  • Document expired for immigration purposes — Spain requires criminal records issued within 90 days of consulate appointment. We flag all timing issues before submission and advise on re-ordering documents where necessary.

CA
California Applicant

from USA to International

Apostille
The problem was…

A California birth certificate was rejected for a state apostille because the notary stamped their seal on a blank white space instead of over the printed text.

Result

Document accepted after resubmission with correct notary placement.

WS

Apostille

The applicant had to dispute the credit card charge and apply properly directly through the California Secretary of State.

Result

Correct apostille obtained after disputing fraudulent service.

Frequently asked questions

What is the single rule that determines apostille vs. legalization?

One question decides everything: is the destination country a member of the 1961 Hague Convention? If YES → apostille from one designated competent authority is sufficient. If NO → full consular legalization chain is required (notarization → state → federal → embassy). You cannot choose your preferred method — international treaty dictates it.

Is apostille cheaper than consular legalization?

Yes, significantly. An apostille involves a single government fee of $10–$50. Consular legalization requires fees at every level — local, state, federal, and embassy — easily totaling $150–$500+ per document, with a total timeline of 4–12+ weeks.

My document was apostilled — do I still need legalization for China?

Yes. China is NOT a member of the Hague Apostille Convention. Documents destined for mainland China require the full consular legalization chain regardless of any apostille attached. An apostille stamp on a China-bound document is completely invalid and will be rejected.

Does an apostille expire?

The apostille certificate itself does not expire — it certifies a historical fact. However, the underlying document may have a strict validity window for immigration purposes. Spain requires criminal record certificates issued within 90 days of your consulate appointment. Birth and marriage certificates are typically required within 6 months.

Canada joined the Hague Convention — do I need apostille or legalization for Canadian documents?

Canada joined in January 2024, so apostille is now legally valid for Canadian documents. However, some Spanish consulates were still accepting the old legalization chain during the 2024–2025 transition period. Always verify with your specific consulate before submitting.

Can I use an apostille for UAE documents?

UAE joined the Hague Convention in February 2021, so apostille is technically valid. However, some local UAE authorities and free zones have their own requirements that may still request the old legalization chain. Verify with the specific receiving authority before submitting your documents.

Does the apostille or legalization translate my document?

Neither process translates your document. The apostille and legalization chain both authenticate the origin and signatures of the document — they do not change the language. After completing either process, if the destination country requires documents in their language, you must also obtain a sworn translation separately.

What happens if I use apostille for a non-Hague country by mistake?

The document will be rejected by the receiving authority. Non-Hague countries do not recognize the Hague framework. If this happens, you must start the consular legalization chain from the beginning — which means additional fees and weeks of processing time. This is one of the most expensive errors to fix, which is why we verify the destination country membership before processing anything.
