My experience was the best I have had…

My experience was the best I have had using a process server! Four contacts was all it took; 1 was requesting estimated cost for service; 2 was transfer of documents; 3 was invoice and payment; 4 was confirmation of service. Was simple, direct and time efficient. I will definitely use this service again.

Great Customer Service and Fast Document Delivery…

I was impressed by the service I received from One Source Process. Nancy followed up on my request and kept me posted the whole way. I received my apostilled document in Mexico in less than two weeks from the date of my order. I am very happy with the service I received from One Source Process and would recommend them highly.

About the time our apostilled documents…

Update: Our documents are due to arrive via overnight mail tomorrow morning. Lots of apologies and offers for upgrades, etc. Thank you. 4 stars.

Original: About the time our apostilled documents were due from you originally, you informed us the State Dept. person you usually work with "is no longer with the office." Then you said the two week clock would reset ending today. We have yet to receive our docs back. We are leaving the country this weekend. 1 star

Reply from One Source Process

Hi Greg,

I completely understand your frustration and please accept our sincere apologies for the delay on your apostille.

This is unfortunately out of our control. We have been at the State Department on a daily basis and are being told by staff that the delays are due to a change in management.

They have not given us a clear timeline on when things will be back to the previous 10 business day turnaround for in person filings. However, we are in contact with their team and will continue to keep our clients updated.

Best regards,

Brandon Yoshimura
CEO, One Source Process

Excellent service

Excellent service! There was an unexpected government delay (which was completely out of their control), but Kristen and her team quickly provided an official letter from their company for me to send to my destination. They were also very helpful and fast in accommodating a last-minute change to an international shipping address at no additional cost. Highly recommend!

Incredibly fast turnaround

Incredibly fast turnaround. I ordered a certified and apostilled copy of our marriage certificate and we received it (in Europe) in less than 2 weeks. A very streamlined process, from beginning to end, including getting notaries and tranlsations lined up to setting up delivery to Europe. Not cheap, but definitely worth it.

They answered all my questions quickly and clearly. The service was delivered on time—actually, a couple of days early! This was a total lifesaver for us, as we didn't have anyone in the US to handle the legalisation process for our document apostille. Highly recommended!

With the anxiety I was feeling around this process, they completely made this process seamless and help take some stress off my shoulders. Honestly completely appreciate the assistance, attention to detail and follow through of this company.

The service was overall very quick and precise.

I was very satisfied with my service.

Thank you for your work.
