Just wanted to give everyone an update on this topic. We went to the US consulate this week to file CRBA and get first passports for the kids and fortunately after a 2.5 hour wait, they were approved. We couldn't find any direct evidence of my husband's physical presence in the US during this first 7 years. He does have passports from age 10 to present and university transcripts which proves that he was in the US for just under 4 years before the children were born. So this is what we submitted: 1. College transcripts of husband's father during the time before my husband was born and till age 5. 2. Husband's original birth certificate 3. Stack of photos of my husband taken when he was a child in the US. We included a couple of birthday photos with his name on his birthday cake. 4. All original passports of my husband with entry stamps to the US from the age of 10 till birth of first child. 5. Husband's college transcripts. 6. Pre-natal records, scans for each child, photos of my pregnancies, family photos showing the kids growing up. 7. A long declaration on the last page (the additional information sheet) of the CRBA form DS-2029 explaining the evidence we present and why we presented them, and a calculation/estimation of the total number of days of physical presence. We really made an effort to present as much relevant evidence as we could gather. Even though we did not have any records of my husband's physical presence in the US during his first 6 years, we wrote that it was because he did not go to daycare back then but hoped that his father's college transcripts will help support that. The officer who interviewed us was very thorough. She said we presented a lot of evidence but reprimanded us for applying when the kids were 8 and 10 instead of when they were babies. She asked us why and we just told her the truth. We explained that we thought we had the choice to do so up until the children were 18 so we didn't see the urgency, but now that we want to move to the US, we would like to get the passports ASAP. She also asked the kids a few questions. My suggestion to anyone who ever gets into the same situation or when dealing with the US consulate is to present as much relevant evidence as possible in an orderly manner, summarise the evidence for the officers, present to the officer that you have made your best effort to gather the evidence/documents and why you might be presenting alternatives, remain calm and tell the truth. I'm relieved that this has go through smoothly. Next step is my visa interview in GZ!
