Sorry I think you misunderstood, the hardship is not from escaping the US but since both of us are working and with the baby it will be very hard to struggle with work and childcare. We are not earning high enough to hire a full time nanny and we have no relatives here.
The reason we are moving out of US is because there is no hope to get a greencard with our country of origin due to long wait time and the H1B visa has a limit on how long you can stay.
Not to sound like an a $$ but if you think bringing up kids is a hardship, half of Canada is in the same boat. Its called parenting and something you have to consider before having a child. but i shouldn't be the one telling you all this.
Perhaps look at Super Visa for your parents for the time being. They can stay for upto 2 years at a time and help you out.
If you have both sets of parents available to help out, It could actually work out for you for the next 4 years (even longer if you alternate their visits)
It just might be better for you to withdraw your application for 2017 voluntarily and re apply for 2018. with CIC, it is usually very black and white. If you are short even by a few hundred, rules are rules and i doubt if application processing officers are at the discretion to make decisions on the fly; only appeal court judges most likely can make those kinds of decisions.
So, as others have mentioned, you could wait till your previous application is denied, then appeal, and wait for appeal court decision which will most likely take longer than just withdrawing your current application, and then re-apply in 2018 where you meet all the requirements.
