Incredibly fast service! I needed my FBI background check apostilled for a visa application to live abroad and they were able to do this in 9 business days. If I were to have gone through the company that processed by background check, they quoted me 6-8 weeks, which wouldn’t have worked. Truly so grateful for this quick turnaround and everyone I spoke to was so helpful!

I am very happy with this service. I received my Apostille in half the time I was quoted. Being able to also have is translated only a few days later was helpful as well. I would recommend this company. The price was a little high for my liking. But at the end of the day, the services was worth the money.

Highly recommend! One Source Process took the time to ensure that my documents were correct before I submitted them for the Apostille service. They recommend us what we need to do for getting the correct ones. They were outstanding helpful with the delivery from U.P.SThey provided everything we needed and returned thedocuments quickly. Super quick and efficient.

Top notch customer service like they have is seldom seen anymore. They were very informative, communicative, professional, and FAST. I had to have my birth certificate apostilled on very short notice and I thought it'd be impossible, but One Source Process made it happen. The rush service was worth every penny. 10/10 would recommend. Thanks again, One Source.

I am so pleased with the service from one source apostille! I have been disappointed by other companies in the past, but they were exceptional. I am living abroad and I frequently need apostille services. I have already referred several colleges to them and I will use them in the future.

Wow I am so grateful for this company!!! I needed Apostille fast for my job and became extremely scared and felt hopeless when found out that the process takes forever if I were to do it myself (or with other company). That is why I am so thankful that I found this company and I really appreciate their help and expertise handling this matter so quickly. I highly recommend them A++++++++++++.

One Source is extremely efficient and responsive. They helped me get documents certified with DHS and Apostille from the State Department. Special thanks to Nancy Rivera for getting on the phone with DHS to clarify to their staff what certifications were needed. Highly recommend for excellent customer service.
