Immigration and Nationality Law Committee

The Immigration and Nationality Law Committee is concerned with all aspects of immigration and nationality law on a worldwide basis, including business-related immigration, family reunion policies, refugees and compassionate cases.

The Committee aims to provide a forum for the discussion of comparative data on immigration and nationality policies of countries worldwide.

The mission and focus of the committee is to provide a platform for lawyers practising immigration laws to receive input and update about the immigration laws of their country and also immigration laws and procedures of other jurisdictions. We achieve this by holding annual conferences and presentation of papers, newsletters and providing other online resources to enhance the knowledge of its member in multiple jurisdictions.

Citizenship revocation, misrepresentation and international atrocity: Sosa Orantes expands current jurisprudence

The 2026 Federal Court decision in Minister of Citizenship and Immigration v Sosa Orantes represents one of the most significant modern applications of Canada’s citizenship-revocation framework to allegations of international atrocity crimes. This article situates Sosa within the broader landscape of Canadian revocation jurisprudence, particularly the post-war cases involving concealed Nazi affiliations. It argues that Sosa marks an evolution in how courts handle evidentiary complexity, assess international human-rights conduct in civil proceedings and reconcile the integrity of citizenship with principles of fairness. By comparing Sosa to Oberlander, Katriuk and related cases, this article demonstrates how the decision reinforces that Canadian citizenship is not immune from revocation when procured through the concealment of crimes against humanity.

The H-1B cap season in 2026: wage inflation and a $100,000 barrier to entry

The latest H 1B cap registration cycle has unfolded amid unusually rapid and significant policy shifts driven by the Trump Administration’s restrictive immigration stance. Although the H 1B programme has long faced incremental regulatory tightening, recent developments mark a more profound transformation. Two measures in particular, the adoption of a far more aggressive prevailing wage structure and the introduction of a $100,000 fee via presidential proclamation have reshaped not only programme mechanics but also the pool of viable participants. Collectively, these changes signal a move away from a high volume, lottery based system toward a de facto merit and capital based selection model.

New global mobility challenges: a guide for multinational corporations in 2026

In 2026, US employment immigration has shifted from a predictable system to a high-cost, merit-based framework. Key changes include a $100,000 ‘entry fee’ for overseas H-1Bs, a wage-weighted lottery and intensified vetting. These barriers are transforming global mobility into a strategic capital expenditure. Consequently, multinational corporations are pivoting toward distributed models, moving roles to satellite hubs in Canada and Mexico to avoid prohibitive costs and administrative delays. This ‘pay-to-play’ environment is pricing out mid-sized firms, creating a specialised labour vacuum and redefining immigration as a boardroom-level geopolitical strategy.
