Immigration & mobility
Acquiring Luxembourg citizenship
Luxembourg citizenship is acquired mainly through naturalisation, which as a general rule requires five years of lawful residence, passing the Luxembourgish language assessment at level A2 (oral comprehension) and attending the civic instruction courses. Other routes exist (option, recovery). The firm guides you towards the appropriate procedure.
Several paths lead to Luxembourg citizenship depending on your background (length of residence, descent, former nationality). The right choice speeds up and secures the process.
Cerno Law Firm identifies the fastest route for your situation and prepares the file.
