The quality of virtual assistants, whether based in the US or outsourced abroad, varies on an individual basis rather than their geographical location. While US-based virtual assistants may have a better understanding of local culture and nuances, outsourcing to foreign virtual assistants can provide access to a diverse talent pool and potentially lower costs. The key is to evaluate the qualifications, skills, and experience of each virtual assistant candidate, regardless of their location, to ensure they align with your specific requirements and expectations.
