Do you understand that the employers are granted visas by nationality? That is, the hiring company holds a certain number of visas for those of specific nationalities. It's easier to obtain visas for Inidans and Filipinos, I'm afraid. Nigerian visas are next to impossible. When the employer says "too bad you're Nigerian" he may sincerely mean it. He would like to hire your husband but can't get the necessary visa.
