We Specialize in California Apostille Service

One Source Process is not new to the apostille process. We have been helping people just like you receive an apostille or embassy legalization since 2023.

We offer a range of services for personal and business documents. Documents include birth certificates, marriage certificates, diplomas, transcripts, FBI reports, power of attorney, and much more. Our team will handle acquiring the apostille of the documents. We will work with the correct California state offices, the federal office of authentications, and if needed, the Embassy or Consulate.

Whether you are located in San Francisco, Sacramento, Los Angeles, or any of the surrounding communities, we take care of the entire process for you, saving you time and hassle. Our offices are headquartered in Los Angeles, California, but we provide our services to every state, especially California.

Working with us is easy. Once you have the correct paperwork, simply fill out the Order Form and either upload your documents or send them to us via mail. We will review all information for FREE and let you know of any missing or wrong information. Because even the smallest of errors can cause a delay or rejection in the process.

Items we review for are:

• Some documents require a notary’s signature to receive an apostille
• Some documents must NEVER have a notary’s signature
• We can accept some certified copies of papers
• In some cases, we must have the original documents

But don’t worry, we will let you know all the rules and regulations for each document, and for each country.

When we are confident that all the documents are correct and ready, only then do we send you a pricing invoice and timeline for completion. With other companies, you often have to pay upfront before you know if you have everything needed.

When we receive the apostille or embassy legalization, we will mail the original paperwork back to you via FedEx or DHL. You never have to leave home.
