Christian H. Kälin or Kaelin[2] (born 1971) is a Swiss businessperson, author, government advisor[3] and lawyer who is the chairman of Henley & Partners,[4][5] an architect of citizenship-by-investment programs that allow wealthy individuals to obtain additional passports.

In his teenage years, he began collecting immigration and citizenship laws from different countries, writing to embassies to request copies of their legislation and keeping the documents in a big binder.

He told writer and journalist Atossa Araxia Abrahamian of this time in his life: "What always fascinated me was the inclusionary and exclusionary aspect of citizenship....I wanted to understand how different countries handled this.

[16] He is a member of the governing board of the Investment Migration Council,[23] and founder and chairman of the Switzerland-based non-profit organization, Andan Foundation.

[20][24] The organization, with board members including Mohammed Nasheed, Mikael Ribbenvik Cassar, Taavi Rõivas and Michael Møller, works in the field of supporting refugees.

[26] The firm restructured St. Kitts and Nevis's citizenship-by-investment program, incorporating donations to support the country's transition to tourism and services following the closure of the sugar industry in 2005.

[33][34] The St. Kitts and Nevis government outsourced its escrow services and application processing to Henley, as well as paid the company to promote the country's program internationally.

[34] According to London School of Economics Professor Kristin Surak, the precise dynamics between Henley and St. Kitts and Nevis are murky, as "there are virtually no accessible records of the negotiations, and those involved in the development of the program offer few details when asked."

According to 2022 reporting by the OCCRP, there is evidence that Henley CEO Christian Kälin helped to finance the successful 2010 re-election campaign of Denzil Douglas, the St. Kitts and Nevis prime minister.

[38] Arton Capital, a competing firm, filed a judicial protest, appealing the decision to award the contract to its competitor, claiming that Henley & Partners provided consultation to the government on a similar program before.

[42] Leaked email exchanges between top Henley officials (including CEO Christian Kalin), Malta prime minister Joseph Muscat, Justice Minister Owen Bonnici and Individual Investment Program CEO Jonathan Cardona discussing launching a SLAPP (Strategic lawsuit against public participation) lawsuit against Galizia that was intended to financially cripple her for her reporting.
