I did my PHD in Germany but we work in large international collaborations, so I meet s lot of phd students from other countries as well. Doing a phd in physics is everywhere I know at least a full time job. Often, depending on topic, group, supervisor and yourself even more than a 40 hour week. The complexity, depth and specialization required don't really allow for anything else.
