An intensive course under §16f means daily classes on weekdays with at least 18 units per week. Distance learning, evening and weekend formats and integration courses are generally not recognised. Plan several months lead time: embassy processing times vary widely; incomplete documents are the most common delay.
Whether you may work during the language course is not uniformly regulated. Clarify that with your embassy. Phonem provides course-related documents; passport, insurance, proof of funds and other application documents you organise yourself.
