Our History

My name is Javier Segura, I am an attorney specialized in Immigration Law and Founder of Cassiopeia Immigration Services.

I started my professional career when I was very young by joining some of the largest and leading law firms with worldwide recognition such as Baker & McKenzie and Marval, O´Farrell & Mairal.

At Baker & McKenzie, I joined the Corporate Department and learned everything about how to register -and provide legal advice- to Foreign Entities. Next, I joined Marval, O´Farrell & Mairal, where I had the opportunity to rotate throughout different practice areas inside the Firm (Labor & Employment, Corporate, Competition and Tobacco Law) which allowed me to try different law practices, industries and to represent many large Multinational Companies of multiple industries.

I consider myself very lucky since I was able to build my professional career by working close to the most prestigious lawyers of Argentina, learning the best market practices from them.

At Marval, although I was not much convinced, I started to take my first steps in Immigration Law. Little by little, I gotten to specialize in the different visa procedures until I turned out to be the focal point at the Firm.

I had direct contact with the clients and many other internal consultations from those Partners who were the Head of their specific Law Practice such as Labor & Employment, Tax, Corporate, and Oil & Gas among others.

These Partners understood the true meaning of integrating the immigration services as a key element to provide a comprehensive advice to their clients.

My next professional jump was at Amdocs, a Multinational IT Company with HQ in Israel, with more than 18K employees around the world, as Mobility Manager for the CALA Region. At Amdocs, I learned the true sense of the word “urgent” and the organization´s true need to count with available resources in a timely manner to support their projects; I definitely understood that the business does not wait. I was the business partner of the company´s stakeholders (HR, Recruiting, Travel, Project Management, and other specific Business Units) that were involved in the relocation of resources throughout Latin America and the Caribbean. For this purpose, I developed strategic alliances with top tier Law Firms across all LATAM countries, and jointly coordinated these immigration procedures in harmony with other regulations such as Labor & Employment, Social Security, Tax and HR Practices.

Finally, I participated in the start-up of Fragomen Argentina, the Multinational Leading Immigration Law Firm, holding office as the Country Manager. At Fragomen, I completed my immigration profile in full. During my role as Head of the Argentine Office I managed to become a key focal point in the immigration industry, representing the largest multinational companies with Headquarters in the country.

I acquired a holistic approach of the business and learned the best practices, processes, and tools of this particular industry.

Nowadays, I founded Cassiopeia Immigration Services, consolidating all the things that I have learned during the different moments of my professional career, to advice on the new requirements set by the market, where the challenges are triggered by new factors such as the Millenial Culture, Diversity and IT Innovation which definitely cross any country border.

I am very grateful for all these opportunities, challenges and for all the people that contributed to my personal and professional development; I really hope I can provide a service of excellence to our current and future clients.
