When will you have finished your masters thesis? If you have not finished it yet you should provide some kind of information or letter that clarifies when you will have finished it and that you will indeed finish it. Otherwise there is a risk that you will be found not eligible for the position as it requires you to have a masters degree.
还有导师说的这个some kind of information or letter,是我自己写的吗还是学校给开的，我已经给学校说了，学校说他们可以开证明说dissertation的ddl是什么时候，然后大概什么时候能出分数，这样可以吗？
