Great service overall
It took much longer than we expected, but considering it was in the middle of government shutdown it was overall great experience

Not the first time we've had to operate under a government shutdown, but this one was especially long. We greatly appreciate your understanding and business Vladimir! Thank you for the review as well!

Thanks so much for the business and review Jexsenia!
Easy ordering
I needed my background check (Nov)apostillized before January. I was nervous with the government shutdown and if that would impact the process. After researching; I’m happy I decided to use One Source. My questions were answered quickly and my paperwork was completed in 2 weeks 1day. I chose the email & 1 day option.
It was well worth the fees.

Very clear and efficient process
Very clear process, good price for services and efficient. I received my apostilled document in a timely manner. Customer service was also very frank about what to expect and I really appreciated that, after receiving escalating amounts from another service within a two day timeframe, which left me feeling like that particular company were scammers.

I have used one source several times for Apostilles and they never fail to deliver. They are swift and efficient, however, they can be a little bit pricier than other similar services but you get what you pay for.
