A person who leaves his/her own country to live in another country permanently

Emigrant

The answer is emigrant.

• Vagabond means a person who wanders from place to place without a home or regular work.
• Mercenary means a professional soldier who fights for money.
• Emigrant means a person who leaves his/her own country to live in another country permanently.
• Immigrant means a person who comes to live permanently in a foreign country.

The word emigrant is the most appropriate because it specifically refers to someone who leaves their home country to live in another country permanently. The other words do not have the same connotation of permanent relocation.
