Warsaw seems to request all the passport pages, then about a month later, they request that the actual passport be sent to Moscow (for those who require visas).
Anyway, here is what I'll be sending:
-Health insurance quotes, for myself and my spouse, since neither of us will be covered for our first bit there
-I'll be contacting some doctors in the city for follow-up treatments of a health problem I'm currently dealing with here.
-A letter from my current employer, stating that my contract ends at the end of May, and that I will be leaving the country at the beginning of June. It will also state that I have not signed nor been offered a new contract.
-My plane tickets
-Several job applications/confirmation letters, that they have received my application
-Receipts from the currency exchange office, showing that I've exchanged most of my money into Canadian dollars
I hope that's enough for them.
