My husband is a green card holder and Gabonese passport , he wants a visa to go to Europe on the 13th of March , what to do??

Hello. First field the online application, and book your appointement for interview at the embassy. Proof of employement, last 3month bank history, flight reservation showing his itenary. Invitation from the host in germany or Hotel reservation .1 passeport picture and visa fee.$69.. Hope i was helpful...😁
