What is the minimum I need to be able to come to Germany

The Immigration Law for Skilled Workers in Germany gives the answer here.

The minimum requirement is that you have a two-year education in a profession and the degree is certified by a state-recognized institution.

This includes universities, colleges, and educational institutions that are accredited by the state. For example also Tesda or other technical educational institution.
