Majority of our relationship started in the US

[LorRie 37]

I (beneficiary) was previously in the US for school (certificate programs, then graduate school), as well as the OPT work program.
I am now back in my home country (around 5 months now) and my fiance, the US citizen/petitioner, and I are working on the K1 visa. 

Our entire relationship of 2 years had been built while I was in the US, so most of our trips/photos/celebrations are from our time there. We've only travelled outside US (Canada) once.
For proof of meeting in person within the last 2 years, I have all the copies of our trips / plane tickets to different cities / photos with his family + friends.

1) My question is, do I / SHOULD I .. include in the packet, the passport stamp where it shows I was admitted into the US? It is kind of obvious that I was in the US as they have all that information on their end, plus, most of our dating timeline (with photos / plane tickets / hotels / celebrations) happened in the US landmarks, cities and states. Would it be overkill to include?   

2) My second comment: does anyone have any tips for a smooth K1 visa process for couples that started dating/fell in love in the US? I don't know if I am overthinking this visa journey but I see it going either way! I feel like I either have more to prove (especially for someone who had been studying on an F1 visa)...  or hopefully, less to prove (shows that I had been there legally + our relationship is genuine as we were pretty much attached at the hip  )

I met my husband while I was in the US. I didn't include any stamp on passport or anything, as I believed the USCIS could easy access to those info if they need to. I only attached a couple pictures of us in the US. No picture else where as we never travel abroad together. I passed all the process without having any problem. Just a bit of a long talk at the US embassy in my home country about how we met but everything went well.

1)I did not include the passport stamp, but I did include many pictures of our time together in the US, and then when he visited me outside the US

2) I was on an F1 visa, OPT as well. I was super scared too, but it was very smooth as long as you write up your story and show pictures showing you guys are truly in love.
