You need 2 copies of passport page 2 copies of embassy letter ( does not need to be original, i printed mine in colour) 2copies of entry stamp and, I took a receipt from apartment where i am staying it was accepted go early I went yesterday at 9.50 and was number 244 - you get number from outside to get paper work tested then when checked they give you a number to go upstairs with - I was told to attend today after 1pm to collect passport
I realise it is not a holiday any longer but lot of flights have been cancelled I am now owed from 2 such flights one who will not refund and only issue voucher for future travel and another that have told me refunds take about 45 days so am unwilling to risk losing any more money to airlines only to have no money to feed myself if they cancel again
