In brief
Swiss settlement permission and Swiss nationality are different; temporary permit retention is not an indefinite overseas residence entitlement.

Identify the canton and permit
Next stepPractical preparation: give the issuing canton the permit type, nationality, family situation and reason/duration of absence. Ask for the procedure relevant to your own canton instead of treating a cantonal example as a nationwide application form.
Check loss and temporary retention
Zug explains that, without deregistration, B and C permits expire after six months abroad; a temporary C-permit retention can be granted for up to four years with genuine return intention and qualifying circumstances. A definitive departure needs its own assessment.
Apply before permission can lapse
Zürich guidance states that retention is discretionary and requests must be made before six months abroad expire. Definitive deregistration can already cause loss; coordinate any retention application before departure. Returning after the approved period generally requires a new admission assessment. Obtain a written decision from your own canton.
Agree the India citizenship sequence first
Practical preparation: obtain case-specific written guidance from the Indian citizenship authority and the foreign nationality authority on eligibility, assurance, effective dates and travel documents. Do not renounce citizenship in anticipation of an unapproved Indian citizenship application. Moving to India or obtaining OCI is a separate decision.
Use the canton-of-origin citizenship process
FDFA describes renunciation for Swiss nationals resident abroad who hold another nationality or are assured of acquiring one. Apply in writing to the responsible canton of origin; its authority decides and notifies the release. Return Swiss identity documents for cancellation and review the specific conditions for including minor children. The Swiss mission can guide the process.
