The travel and events company, which has a dedicated in-house Passport & Visa service, released advice for clients concerned with the potential business impact the Games will have on London's transport and delivery infrastructure.
The advice contains information on delivery times and schedules of the Royal Mail and various private Courier Services and information around dealing with requests to Embassies and Consulates.
With many organisations expected to operate with a skeleton staff, reduced working hours and amended delivery schedules during the Games, ATPI is advising client's to allow extra time for all aspects of document processing and submit requests as far in advance as possible.
Graham Ramsey, chief executive, the ATPI Group said: "Our business has put in a huge amount of preparation to ensure our various departments, including our Passport & Visa service, are ready for the 2012 London Olympic Games. The arrival of the greatest show on Earth is undoubtedly going to put a massive strain on the city’s infrastructure and we are working with our clients who still need to fly on business during the Games to ensure, that wherever possible, it’s business as usual."
