Dear officer,
I hope everything goes well.
Can I ask if the CBS can provide an invitation letter for visa application? The visa application website mentioned the "Invitation letter must be written on official paper or VU1 filed form and signed by the host mentioning clearly: purpose and duration of your stay; detailed program and itinerary; an indication of the costs and entity that will pay for them; Data and contact details from the inviting host abroad."
I am looking forward to your reply.
Best,
Zhe
