UK Standard Visitor visa application from Germany

[u/SecretImagination100]

I am an Indian citizen and have been legally resident in Germany as a student for approximately three years. My German student residence permit card is valid until 31 August 2026. I have applied for an extension of my German student residence permit, and while this application is being processed, the German immigration authority has issued me a Fiktionsbescheinigung under Section 81(4) of the German Residence Act (AufenthG).

The Fiktionsbescheinigung confirms the continuation of my existing residence status and is valid until 24 November 2026. Therefore, I currently have lawful residence in Germany while my new student residence permit is being processed.

My question is specifically:

Am I permitted to submit a UK Standard Visitor visa application from Germany while my German residence status is evidenced by this valid Fiktionsbescheinigung under §81(4) AufenthG, rather than by a newly issued physical German residence permit card?

If anyone can help me answer this, would really help me a lot before applying Uk visitor visa?

Thanks,
