Testimonials from real clients

Keven Smith
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.

We have used a few different process servers and no one has provided the level of customer service that One Source Process has. They are very reliable and they communicate every step of the way. Alex and Brandon have been a huge help and they always take their time to understand our needs. We look forward to working with One Source Process for a long time.

I used this company for Chinese Visas and they were the best! If you need a visa, use One Source Process! I was worried when choosing a company to get visas through since we would have to send in our physical passports and all of the personal info you need to provide. They made everything smooth, easy, and always answered back to my emails within hours, if not minutes. With all of my questions and concerns, the constant communication really helped put me at ease. I can not recommend this company enough!
