Good day to all! I am just wondering if someone can help me, how long it takes for a K1 visa correction. My surname was misspelled and when I ring the US embassy they can't give me a timeline. I already returned my visa together all docs as they required. Please help me.

Nobody here works for any agency who handles passports or visas. You need to deal directly with them. I hope you sent them by a method that provides tracking and delivery confirmation. If the Embasy can't give you a timeline...we certainly can't.
