The host unit in China, where I was going to do internship, inquired a visa notice to Chinese government but receved a refusal. The reason is that I haven't received an italian stay permit yet. I would like to remind that in february I came to Milan from Kazakhstan for studying master in the university and applied for permesso di soggiorno once i arrived. But it is still being processed. I sent to China my passport's page wirh annual italian visa and postal receipts confirming my application for permit but the answer was they need only final document, the permit.
It isn't clear to me why chinese government requires my italian stay permit if am a resident of Kazakhstan, now I am staying in Kazakhstan and was going to apply for a chinese visa in Kazakhstan.
