Hello, I have my H1B stamped recently, but my wifes H4 is not valid. I have business trip to europe and during this time would it be possible for my wife to get H4 stamped in US consulate in Germany/Denmark ? Thank you

You can apply in any US embassy unless the embassy specifically blocks third country nationals.

Hello Anil, thank you, but could you please clarify bit more? Becz, what reason shall I give to my wife? stamping VISA reason? She could stay in Denmark in my cousin home for e.g., is that a risk? or what you think?
