Belgium immigration lawyer
Our Brussels law firm combines two fields of special expertise practised by two complementary teams: a team of lawyers specialised in immigration law and a team of lawyers specialised in public, administrative and constitutional law.
Altea’s immigration lawyers can provide you with an extensive and varied range of counsel and assistance services.
Examples of our areas of expertise in immigration law are explained further and categorised on this website under three main areas of expertise: the rights of foreigners, international family law (also known as private international family law) and nationality law. Please feel free to consult the legal information provided on this website. The information can, for instance, answer your questions on family reunification or marriage with an undocumented person or provide you with guidance in dealing with the Immigration Office, etc.
The list does of our expertise as immigration lawyers is not exhaustive. Altea’s immigration lawyers can provide you with useful guidance and counsel for many immigration-related questions. In the event of an administrative or legal procedure, Altea’s lawyers can represent you domestically as well as internationally (European Court of Human Rights, European Court of Justice, etc.).
Altea’s vision of the lawyer profession and of its founding principles is consistent in our handling of our various files. The firm brings together highly specialised and accessible lawyers. The specialisations practised at Altea complement each other and the firm’s lawyers all share an interest in defending human rights.
The “news” page on the website also contains legal information on immigration law.
Altea can provide you with the services of an immigration lawyer who is an expert in your situation.
