Released on 8 July by Bloomberg agency, the so-called Henley Passport Index is produced by the law firm Henley & Partners, which defines its activity as "residential and citizenship planning", based on information provided by the International Air Transport Association (IATA).

However, the strength of the main passports appears diluted when considering the restrictions on travel in the context of combating the pandemic.

In fact, Henley & Partners CEO Juerg Steffen, in an article that follows the index, noted that "the pandemic has eroded away the strength of 'premium' passports."

In this sense, the apparent strength of those documents appears in fact weakened by the various limitations on international circulation.

Henley & Partners President Christian Kaelin considered it clear that global mobility “is going to be severely limited for at least 2021” and that, in this situation, “people need to expand their residency and passport options”.

In this regard, this law firm points out that in around 100 countries, including 60 percent of the Member States of the European Union, there are programs for access to residency or citizenship, starting at $100,000.
