One Source Process worked very efficiently and quickly to get my apostille done in the timeframe that I needed. I highly recommend them to anyone who needs their services, they made sure to contact with me with any pertinent information regarding my apostille and answered any questions that I had. I'm very satisfied with my order and highly recommend them to everyone!

Apostille documents
I used OneSource Process to get documents apostilled to apply for a visa in a Central American country. This was my first time getting anything apostilled and OneSource Process made the process very easy. I uploaded the documents to their portal and the next day, I received an email with an itemized quote of how much it will cost to apostille the documents. I appreciate the fact that they are transparent of what you're paying for BEFORE you pay for it.
My OneSource Process reviewer informed me via email that one of the documents I submitted required that it be notarized before it was apostilled. They gave me 3 options to get the document notarized (I could do it in my home state (OneSource would send me the paperwork I would need for my state) or I could have OneSource do it). I preferred to have a one-stop shop, so I had OneSource notarize it before having it apostilled.
One thing that I really liked about OneSource is that they had an option to receive a scanned copy of my documents once they were apostilled and before they FedEx'd the hardcopy documents. I opted to get a scanned copy of the documents because I knew that I wanted a copy of the documents anyway and it saved me the step of scanning the apostilled documents myself. The entire process took 2 weeks from start to finish (from when I first uploaded my documents to when I received the apostilled documents in the mail).
OneSource Process was very responsive, efficient, and they kept me informed of the status of the apostille process as well as when the documents were mailed back to me. It truly is a one-stop shop. I highly recommend OneSource Process for your apostille needs.

Fast, efficient, and great communication
The process was very simple, and they kept me updated at each step. Altogether it took 2 weeks - well worth the fee given my previous document mailed to the FBI took 12 weeks to return. You're getting extra peace of mind with One Source Process.
