My 2nd passport (see attached scan) is specially for the use of visa applications while traveling on the 1st passport, both are valid travel documents but need to carry my 1st passport with my 2nd passport when traveling overseas as my 1st passport has my visa in it.
So when I leave my 2nd passport with you after I pick up my first passport with Indian visa, you will need to make copies of previous entry visas for China and my Thai visa with so you can take this with my 2nd passport for visa application.
I don't need an Australian visa as I'm a permanent resident of Australia.
I will request the invitation letter from the company in China again but like usual, they will not organize a government letter.
