BLS International accepts applications for national visas in the interest of the Slovak Republic on the basis of instructions with lists of specific applicants from the Embassy of the Slovak Republic in Astana.
If you failed to register for a specific date, it means that the instruction to accept the applicants you listed has not yet been received by the BLS International visa center from the Embassy.
In the process of sending the lists, the time possibilities and staff capacities of the Embassy are taken into account.
At the same time the Embassy informs the Slovak employer of the sending of the instruction to accept the applicants at the BLS International visa centre
