Five typical causes of delays in the Einbürgerungsverfahren (naturalization procedure)

Delays in the Einbürgerungsverfahren (naturalization procedure) often do not originate in the legal examination of the substantive requirements, but at the interface between the application file and administrative practice. From the exchange of experience with municipal Einbürgerungsbehörden (naturalization authorities), migration counseling centers, and law firms specializing in migration law, five recurring constellations can be described that typically lead to follow-up queries or requests for supplementary documents. This account is descriptive; the assessment in the individual case rests solely with the competent Einbürgerungsbehörde.

1. Incomplete identity documentation

Observed pattern: passport, birth certificate and, where applicable, marriage certificate are on file, but are either expired, not translated by a certified translator, or not authenticated in the form accepted by the particular authority (Apostille, Legalisation). In such cases authorities typically follow up and set a deadline for subsequent submission. Extension of the procedure: regularly several weeks.

2. Language certificate not in a recognized form

Observed pattern: § 10 Absatz 1 StAG requires sufficient knowledge of the German language. In administrative practice this is typically specified as CEFR level B1, evidenced by a certificate from a recognized provider. Confirmations issued by private language schools without such accreditation are not accepted as proof in these cases.

3. Incomplete proof of secure livelihood

Observed pattern: § 10 Absatz 1 Nummer 3 StAG requires that applicants be able to support themselves and any dependent family members without recourse to certain social benefits. Authorities regularly examine several years of income and employment history for this purpose. Gaps caused by periods of Kurzarbeit (short-time work), receipt of SGB II benefits, or intermittent self-employment without structured bookkeeping typically lead to additional queries.

4. Criminal record entries below the de minimis threshold

Observed pattern: § 12a StAG governs which criminal convictions preclude naturalization and which are disregarded. Entries that are not declared on the application form, including those that would ultimately not be disqualifying, typically prompt an inquiry by the authority to the Bundeszentralregister (Federal Central Criminal Register) and draw the procedure out.

5. Incomplete residence documentation

Observed pattern: the period of lawful prior residence under § 10 Absatz 1 StAG (five years since 27 June 2024) must be demonstrable through an unbroken sequence of residence titles. Changes between residence purposes (study, employment, family) without fully documented transitions typically lead the Einbürgerungsbehörde to obtain statements from the competent Ausländerbehörde (foreigners authority).

Assessment

The five constellations are of different kinds: points 1, 2 and 5 concern formal completeness, point 3 the substantive requirement of secure livelihood, and point 4 the process of internal clarification within the authority. The assessment in the individual case, including the question of which evidence counts as sufficient and which transitional cases under § 40a StAG apply, rests solely with the competent Einbürgerungsbehörde.
