Hague Apostille Required? One Source Without Hesitation

I submitted an FBI background check for Hague Apostille to the Dept. of Authentications in preparation for an interview for a European visa. With 14 days remaining and no means of communicating with this office regarding documents they received from me 7 weeks prior, I became concerned and hired One Source. Their staff were outstanding- I explained my time constraints, and without making any promises they assured me they would endeavour to get the processed documents processed - the FedEx driver handed me a package 1hr 43 minutes before I was to leave for my flight. Special thanks to Nancy Rivera, she diligently assured the necessary attention to detail before dispatching the envelope. Incidentally, I received my self-submitted Hague Apostile the day I returned from my visa interview.

Fast and well translated.
Needed it for court documents and the judge accepted it. The service was done in less than a week for 2 documents. Can’t complain.

Good Service - Poor International shipping

Overall I was happy with the service One Source Process provided. I ordered a Marriage Certificate from the State of Washington, to be used in Thailand. Cost for their service was $625 USD (including $75 for International shipping). They gave me the procedure needed to order the document and then they handled the rest. They kept me updated as the document moved between each government office. Once the document was returned from the Thailand Embassy they shipped the document back to me, and this is where I was unhappy about the service. The document I paid over $600 USD to be used by the Thai government was shipped halfway around the world in a flimsy FedEx document envelope. The envelope was bent and the document has folds in it and now looks like an unprofessional document. I paid $75 for the international shipping and they could have used an envelope that would protect the document. I understand it was FedEx that caused the damage, but a sturdier envelope would have prevented the damage to the document.

Reply from One Source Process

Hi John,

Thank you for taking the time to share your feedback. I’m sorry for the inconvenience you experienced, and I’d like to offer a refund of the shipping fee as a gesture of goodwill.

While the shipping issue was largely outside of our control, I fully understand how upsetting it is to receive documents that aren’t in perfect condition. In over 15 years of processing apostilles and legalizations, situations like this have been extremely rare.

Because our network spans multiple states and countries, we aren't always able to coordinate the exact type of packaging each of our agents uses. FedEx also does not offer rigid mailers, only boxes, which significantly increase shipping costs for clients, especially for international deliveries. We do our best to balance protection with practicality, and we’ll be reviewing this internally to see where we can tighten our process.

Please feel free to reach out if there’s anything further we can assist with. Expect the shipping fee refund within the next week.

Best regards,

Brandon Yoshimura
CEO, One Source Process LLC
