She has to answer honestly every single time. If she is caught in a lie, it can lead to a permanent ban. She can't change her story now because they already have her admitting to drug use on file.
Okay Update guys!! After my husbands interview on 02/22/2018, they said nothing about him admitting to prior drug use, did not even discuss it. What held him in AP was because our lawyer advised us that the court documents for my previous divorce was enough but they wanted the divorce certificate from the state of Wisconsin. This ended him up in the lovely green slip 221g for Administrative Processing for missing document. I overnight them through ups the same day (cost: 99.68$) the document was received on 02/23/2018 at 5:06 pm, cargo express was now closed. He turned the document in however on Saturday 02/24/2018 to cargo express. The Embassy received the document officially on 02/26/2018. He remained in administrative processing. One 03/07/2018 the status changed from Administrative processing to ready at around 12:35 PM and then switched back to Administrative Processing 30 Minutes after it change. His date updated from 02/22/2018 to 03/07/2018 when this happened. It stayed like that until the morning (9:30 AM) of 03/09/2018 where it changed to Issued (CEAC) and the case status date changed to 03/09/2018. Now keep in mind that the travel website to check your passport since 03/07/2018 kept saying there is no status update available for the passport number submitted. On Monday 03/12/2018 that status for the passport switched to something I can remember it said along the lines of awaiting for delivery that it had left the consulate/embassy. On 03/13/2018 at exactly 6 AM i received an email alert that the passport/visa was ready for pick up! My husband went to pick it up, they gave him the yellow envelope and told him not to open it. Please note: the envelope has a tear in it, and they told him that was normal the hole because thats how they open the envelope quickly when he goes in the us airport through immigration. They also told him not to give the envelope to anyone in the El Salvador airport that the person that he needs to hand it to is the immigration officer in the United States. Now flights are outrages for prices right now due to spring break, 1,400$ to return home so my husband will be officially returning home on 03/22/2018. If all goes well through immigration, he will be home safe and sound. This whole process is nerve wrecking because you are basically trusting in the unknown, I wanted to update everyone because we went through so much anxiety and if it can help alittle bit on the process we went though then great! Message me if you have any questions, it was nerve wrecking, but we waited and we will soon be reunited!!!
If that is the only reason for pending administrative processing, then probably. If there are other reasons, then the embassy will take as long as they need.
