OIS Services Arvostelua 

The staff in the London office are unnecessarily rude and the service provided is poor. They should invest in screens instead of discussing people's business loudly in such an open space.

Excellent and efficient service. Very helpful from the moment I arrived.

I highly commend Mr. Sarab for his exceptional customer service. He demonstrated true professionalism through complete transparency and outstanding support.
While other businesses failed to resolve my BVN issue for over six months, Mr. Sarab sorted it out efficiently. This is the gold standard of customer service.
Thank you
Kind regards

Amazing staff from reception entrance to completion of visa application with Sarab and Zainab

Zainab was very helpful and patient. I appreciate the service she offered very satisfactory.

I am extremely disappointed and frustrated with OIS Services Atlanta. I was traveling for an emergency leave and paid for their expedited visa service, which they explicitly promised would be processed within 48-78 hours. I traveled from California and even told them I would stay in Atlanta until the passport and visa were ready.
After 7 business days of silence, they finally responded saying they had mailed my passport along with the Nigerian visa. The documents never arrived. Since then, I have called them countless times and sent dozens of emails with zero response and zero customer service.
This level of incompetence and lack of communication is unacceptable, especially for an emergency situation. It’s also concerning that the Nigerian government would entrust a company like this to handle most of their visa processes.
I strongly advise everyone to avoid OIS Services Atlanta. They took my money, failed to deliver, and have completely ghosted me. Save yourself the headache and stress.

Very simple and efficient process. Polite and helpful.

Zenab gave me a very special attention and she help me with my application and put me through . She's a wonderful and kind lady l have ever meet and her hospitality to human beings is excellent, including all the staff are doing well to everyone, their hospitality is excellent
