Washington, DC Apostille Service

When apostille authentication is required for traveling abroad, you can either work on your own to obtain one, or work with us and let us handle the red tape for you. Obtaining an apostille or embassy legalization on your own can be a complicated and time-consuming process. We have years of experience working with the state and federal governments. Let us do the hard work for you.

Whether you are traveling out of the country for business, to study abroad, a destination wedding, or any other reason – you may be required to show specific documents. And each of those documents must be authenticated.

Some documents that commonly require an apostille are:

  • Birth certificate
  • Work visa
  • Student visa
  • Single status affidavits
  • Passport
  • FBI background check
  • Social Security letter
  • Power of attorney

Authentication is a certification of the signatures and seals on a document. Papers can either be apostilled or legalized, depending on your destination country.

An apostille or embassy legalization is a certificate attached to the required paperwork to validate its authentication.

Countries that are members of the Hague Convention of 1961 established a uniform acceptance of authenticity called an apostille. All non-member countries only accept documents that have been legalized according to their standards.

But don’t worry if you are unsure if your papers require apostille authentication or legalization, we know all of this for you. We have worked with all states and just about every country; we will properly authenticate your documents.

I highly recommend One Source Process for all of your document legalization needs. I will recommend them to my colleagues, friends, and incoming employees for overseas employment. They tackled two complex problems for me with ease. They communicated well and addressed all my concerns in a prompt manner through email and phone calls. If you ever need document legalization services, call no one else, I won’t.

Professional and efficient - Having not been through the Apostille Service previously, we were guided and taught what we were doing by extremely professional and courteous individuals. We couldn't be more pleased at the efficiency and the speed at which they were able to get the job done. The final product was accepted by the bank and the beneficiaries of the estate received their funds, everyone was happy. Thank you, One Source Process, Inc.
