hi there, well if class 1 is the issue, many countries have their medical centres in different countries, as to assist the crew, look under medical centres in abroad under your respective civil aviation website, and as long as my experience of a a valid med is concerned, out of my three friends who submitted without a valid class 1 only one of them got rejected for a med, so he did it in India and submitted again. I guess they have different rules for for different ppl
. But if u r holder of a PPL then a class 2 is sufficient, acc to international rules.
