French legal advice for international clients moving to, working in, or investing in France
J2M is a Paris-based French law firm advising international individuals, professionals, entrepreneurs, investors, families, and businesses.
Our work focuses on the legal issues that arise when an international project connects several areas of French law. Depending on your situation, this may include immigration, residence permits, business structuring, taxation, investments, or representation before French authorities.
We help clients understand their options, identify the appropriate legal strategy, and take the necessary steps with greater clarity and confidence.
Jean-Jacques Michallon
Jean-Jacques Michallon is the director of J2M. He assists English-speaking professionals, entrepreneurs, business owners, investors, and families who are planning to establish themselves or develop an activity in France.

His practice also includes French immigration and business law, particularly where immigration status, professional activity, corporate structure, and taxation are connected.

- Moving to France as a professional, entrepreneur, employee, investor, or retiree.
- Applying for an appropriate visa or residence permit.
- Establishing or restructuring a business in France.
- Assessing the French tax consequences of relocation, investment, or business activity.
- Responding to tax audits, adjustments, or disputes.

Who we help
International professionals and entrepreneurs

We assist individuals and families with the legal aspects of relocation, including residence permits, family-related immigration matters, and the consequences of establishing a personal or professional life in France.
Investors and business owners
We advise international clients considering an investment, acquisition, business launch, or corporate restructuring in France. Where appropriate, we coordinate the immigration, corporate, and tax aspects of the project so that decisions are made with the wider picture in mind.

An integrated approach
A move to France is rarely only an immigration matter. The visa or residence permit selected may affect your professional activity, business structure, taxation, family situation, and long-term plans.
For this reason, we begin by understanding the wider project rather than treating each legal issue in isolation. We consider your objectives, nationality, family circumstances, professional plans, assets, intended timeline, and current situation before identifying the most appropriate next step.
Our role is to help you understand:
- Which legal route may correspond to your project.
- Which facts and documents are important.
- What risks or alternatives should be considered.
- Which steps should be taken first.
- When another specialist, such as an accountant or notary, should be involved.
