Dear Members,
Greetings! I am new to the forum and would be glad if the community can provide advice on the topic below.
I am a passport holder issued by the republic of India but have a valid work/residence permit in Germany stamped on the passport. I stay in Munich with my family and had planned a short 4 day trip to Switzerland for next week. As per rules, we are allowed to visit Switzerland without a visa.
However, our passports are stuck with the UK embassy in Düsseldorf for UK visas and the UK embassy does not guarantee that I will get back the passports in time

. I have a stamped letter (along with photocopies of our relevant passport pages incl. German work permit - Aufenthalserlaubnis) from Worldbridge services handling UK visa applications stating that our passports are in their possession for UK visa processing.
Can I enter by rail into Switzerland from Germany with only the above stamped letter and photocopies of our passports? Any experience whether the border police would allow us in or not?
The local Swiss consulate in Munich only stated that I may proceed at my own risk

.
Thanks in advance for any hints/recommendation!
