I would contact them if your waiver was approved last Thursday...don't delay. My husband received his approval, immediately after his 2nd interview - while we were still in Juarez...they gave him written instruction on what to do next...fingerprints, turn in passport and so on.
I am so excited for you! I hope you are able to receive permission to return as quickly as possible. God bless.
Congrats, it is most definitely a yes that your I-601 has been approved. Your family member here in the U.S should have received your approval letter by now or shortly in the mail if you used their address as your primary contact address.
Just a heads up that might be useful to some of you. My I-601 was approved on September 8. I'm outside of the US but my son in Florida got the approval by mail yesterday, a few days behind because of Irma. My waiver was filed on August 31, 2016 so It took exactly 1 year and one week to get the approval (373 days) but within the processing times published for the NSC. The next step is to wait for the docs to arrive at my consulate (takes about a week), and for my consulate to email instructions to get my passport stamped with the I-130. There's 2 options at my consulate, they might request that I send a few documents and my passport by mail and they will return it stamped with the visa by mail as well, or they might request that I personally bring them the documents and the passport to be stamped. And that's it, either way they request I should be back in my beloved USA in a few weeks.
My receipt number is LIN1690968145 just in case you want to compare with your own receipt number so you can roughly estimate were you stand at this point. Funny thing is that on the myUSCIS website my case still hasn't been updated as approved.
My case was a complex one, but I was always very positive and always believed that I would get my waiver approved, never doubted it. Not even in my worst moments did I loose hope or focus. I encourage you guys to do the same, be positive, persevere, be patient and believe in what you want accomplished and it will happen, don't doubt it for a second. And of course never underestimate the importance of an outstanding attorney that is also a compassionate human being that listens to you, makes you feel comfortable and answers your questions clearly, understands your story and tells you straight if he can handle your case or not.
In the meantime you can notify the embassy by email that you have filed the I-601 and are awiting USCIS decision. You can also ask them to extend your K1 application during this time. That's what I did. I dont know if its necessary but it made me feel better to let the embassy know what is going on. You can review my timeline.
It really depends on the embassy. Some work faster than others, From what I have seen Mexico usually works fairly quick. Give them at least 2-4 weeks after approval to receive that info from USCIS and prepare your second interview. It won't be long now.
