Hello @VerbalQueen,
thank you for reaching out to the Wefugees community and for sharing your questions with us.
The law on nursing professions provides that nursing schools can refrain from demanding "language knowledge at a level that enables professional practice" at the beginning of your vocational training, but in practice, at least in Bavaria, they want to be shown a B2-certificate until 1st of September.
That is due to the fact that the apprenticeship is linguistically very demanding.
To apply to the schools, your current proofs are sufficient. Don't just send your documents with your application, try to get an appointment and explain your situation. The schools (and the hospitals where you'll be working later) might even benefit from a candidate with practical experience. Some federal states of Germany even accept applicants with a B1 level - as you have a proof there will be a B1 exam in October you stand some chance to get your training postition. You could also try to sit the exams in July or August, if you want to play safe. Some schools offer the DTZ or B1 from July on.
Some remarks about how to secure your residence permit: As a last resort, if no school is willing to accept you, you might apply simultaneously for a voluntary service in nursing at a hospital. This is called "Bundesfreiwilligendienst", and as a rule, the immigration authorities approve a contract to issue a visa for voluntary service if the application has been early submitted. Nevertheless you should ask them in advance.
Another, but not so preferable option would be to apply fot the one-year nursing assistance training position. here B1 is sufficient, and you'll easily get a visa for it. It's not simply wasted time (because you already know a lot more), because this year could shorten the ensuing nursing vocational training from three to two years. Furthermore, it provides you with enough freedom to brush up your German to an excellent B2 level and to gain valuable insights into the German health system and terminology.
