That's just an estimate. As I said repeatedly, it is not for sure until you have the visa in your hand. A lot can still happen between the interview and the actual visa being printed. Even if the CO says he approves your visa, it doesn't mean he hit "print" on the computer at the visa is printed. After the CO approves, he has to turn the file to his supervisor to approve and to the section chief to review and approve and who knows how many other levels at State need to approve a visa before it is "approved". I know, because I work for the government too, and if I want to take my group to go out to have lunch, 5-6 people have to approve it, just so we can go get a sandwich to eat. And then what will happen if one of those people are sick and absent for a week, or the IV section chief takes a vacation in Dubai. Just saying, it's not an exact thing.
Oh come on, it's not that hard. If my 65 years old mother who only speaks 3 words in English could do it, you can do it.
Nobody can tell you accurately how long it will take. We do not work for the embassy.
You have 6 months after the visa is issued to use it. So your husband can come back anytime after that to bring you to the US. Are you can come to the US alone, it is not that difficult.
It is always, always advised to not make travel arrangements until the visa is physically in your hands. Because things like this can happen that cause delays in the process and you not knowing when you will receive the visa.
If your husband has to go back it is not the end of the road. You can prepare for immigrating to the US in the meantime and he can simply make another trip to come get you.
