Be ready to explain every detail. They asked my husband about an entry from 14 years ago. He had several deaths in his family, thought he was drinking too much and sought help from his Dr. He had no other entries about alcohol AND his blood/urine came back clean but they wanted to know all the details from the Dr about that visit. Ridiculous, imo, since there was no other entry, it was from 14 years ago AND their own tests indicated no problems. I'm not trying to worry you, but warning you so you're not blindsided like he was. I have to wonder if all this is our reward for trying to do this process legally and doubt if those streaming across out southern border are vetted this much.
