Hello,Well the baby situation is a curve ball but honestly there's nothing the lawyer is doing that you cannot so yourself.
So if you wanna sum of the birth of the new baby as a time when you were on a break or something to that effect
However, I suggest you get ahead of it don't let them ask you about it so your relationship story might require a couple pages to answer the red flags.
Likely they will ask for an interview and at that point your husband will need to explain in his words why you're the one for him and why he isn't using you. Keep in mind they are doing this to protect you and provided your husband is genuine this will be difficult but doable to pass. They will grill him so be prepared for that.
People date while being separated so thats no biggie and like you just wrote to me explain to them there was no real official title to your relationship until whatever date... keep in mind if the serious date was after conception of new baby there might be an issue.
It seems you and him had a relationship prior to was long distant so you didnt put too much weight on it, he came and you guys realize you have a good vibe and decided to make it serious....
Again what may seem as red flag I see a good relationship story.
I am replying to answer this further for anyone that may do a google search for something similar. I spoke with CIC and they advised me that the charge of Fraud does not fall under the bar that they use for spousal sponsorship.
I should have called them a long time ago...
Good luck to anyone who may come across this tread.
