Usage tips
Word structure
The word is made up of 'Ausland' (foreign country/abroad) and the ending '-er', which denotes a male person. 'Ausland' itself consists of 'aus' (out/from) and 'Land' (country), so literally 'from another country'.
EXAMPLE
Er lebt seit zehn Jahren in Deutschland, ist aber offiziell noch Ausländer.
He has lived in Germany for ten years, but officially he is still a foreigner.
Word family
'Der Ausländer' belongs to a word family with 'das Ausland' (foreign country/abroad) and the adjective 'ausländisch' (foreign). If you learn these words together, you can remember the meaning more easily.
EXAMPLE
Viele ausländische Studierende besuchen deutsche Universitäten.
Many foreign students attend German universities.
Register and style
'Ausländer' (foreigner) is the official, administrative term used in laws, forms, and government offices. It refers purely to citizenship.
EXAMPLE
Für die Einreise müssen Ausländer ein gültiges Visum vorlegen.
To enter the country, foreigners must present a valid visa.

Ausländer vs Bürger
citizen
'der Bürger' and 'der Ausländer' can form a contrast in connection with a state. Here, 'Bürger' means a person who has the citizenship of that state. 'Ausländer' means a person who is in a country but has the citizenship of another state. The words can be confused because an Ausländer can still live in a country. So the decisive factor is not only the place of residence, but citizenship. In your own country, you are a Bürger; in another country, you may be an Ausländer.
Ausländer
Vor dem Termin fragt der Ausländer, welche Unterlagen er bei der Behörde zeigen muss.
Before the appointment, the foreigner asks which documents he has to show at the government office.
Bürger
Tim ist deutscher Bürger und braucht für die Wahl nur seinen Ausweis.
Tim is a German citizen and only needs his ID for the election.
