Applied for B1/B2 visa after current 10 year visa is about to expire. Qualified for dropbox appointment but was apparently called for an interview at Embassy in Delhi. Went for an interview and it went smooth but got 221G (Additional admin processing). We are party of 5 (Husband, wife and 3 kids). When I checked CEAC tracker, it shows approved for wife and 3 kids but refused for husband. Now, we got an email with letter (See attached). Now, the thing is the letter mentions several points that are irrelevant from a tourist visa perspective. So I am looking for suggestions on what points to include in my resume. Is there any format or template available that I can use. Points like Research, Funding, Itinerary are irrelevant at this point as I haven't made any travel plans yet. Any suggestions, advice will be greatly appreciated.
PS: Have only visited US once and stayed for about 3 weeks.
