Some translation companies mention it as a strength that they are based in the Egypt or in the KSA. It's true domestic companies give your more confidence and convenience because you're in the same time zone. However, if you want translation quality, keep in mind they will hire freelance translators to do the job. So, where their translators are based is more important than where the translation company is based. As one of the best practices, it's better to use local translators. For example, we'd better use a Japan-based Japanese translator for English to Japanese translation. There might be good Japanese translators in the USA but for sake of safety, we'd better use the ones in Japan.
