Question I130 Petition Filed by US citizen not living in US- Need help

[JCB2015]

I am a US Citizen by Birth born aboard. I have never lived in the US and I am now looking to move to the US in the summer. My Husband and Kids are not US Citizens and I filed the I-130 Petition for them. I sent it to the physical address in Chicago and it arrived on Friday April 3. Anyone have any idea when I should get receipt that it has been received? Do you think it will be a long process for my kids and husband? my kids are under 5 and I have been married for 4 years now. I just got an SSN number issued and I stated on the application form and I am hoping it gets approved because I am not in the position to leave my 4 yr old and baby 9 months with Daddy for a few months while this gets approved as that's a lot on my husband and of course a lot for me as I will be missing them. We currently live in the Caribbean.

Any suggestions, thoughts?? Will be greatly appreciated.
