I went to the embassy to enquiries with the officials since 27 October. My boyfriend had a conversation with Czech officials about document for long-term visa.
He said if I want to send more documents, no need to queue appointment in the web site because the embassy recorded petition already. And I'm ready to submit additional documents on 23-27 November.
So I sent an email to inquire date and time will allow me to submit additional documents at the embassy, please reply my petition.
