Do trips abroad break the residence period for German citizenship?

Checked on

Germany's Nationality Act says stays abroad of up to six months don't interrupt your habitual residence for naturalisation. Longer stays don't either if you return within the period the immigration office set. But residence as a rule no longer continues once time abroad exceeds half the required residence period. After a break, up to three earlier years can count.

Key facts

What The law says Source
Stays abroad up to 6 months Don’t interrupt habitual residence in Germany StAG § 12b(1) sentence 1
Longer stays abroad Residence continues if you re-entered within the period the immigration office (Ausländerbehörde) set StAG § 12b(1) sentence 2
Military service at home Exceeding the period only because of compulsory military service doesn’t count against you if you re-enter within three months of discharge StAG § 12b(1) sentence 3
Too much time abroad overall Residence as a rule no longer continues if stays abroad exceed half of the residence period required for the naturalisation StAG § 12b(1) sentence 5
After a break Earlier residence in Germany of up to three years can be counted StAG § 12b(2)
Late permit application Gaps in lawful residence because you applied late for your first permit or an extension are disregarded StAG § 12b(3) sentence 1

Short trips

The law says stays abroad of up to six months do not interrupt your habitual residence. For longer absences, what matters is whether the immigration office set a longer period for your return and you came back within it.

The “half” limit

Even when each absence is allowed, the law sets an overall limit: habitual residence as a rule no longer continues once your stays abroad add up to more than half of the residence period the naturalisation requires (§ 12b(1) sentence 5).

If your residence was interrupted

If you were abroad for more than six months and none of the exceptions applies, your residence is interrupted. The authority can then count up to three years of your earlier time in Germany towards the required period. The same applies if you exceeded the half limit (§ 12b(2)).

Gaps in lawful status

If your residence was unlawful for a while only because you applied late for your first residence title or its extension, the gap is ignored. Other gaps in lawful residence are treated like the break above: up to three earlier years can count (§ 12b(3)).
