US Immigration from Spain

Guys,

I am getting ready to submit the complete CR-1 paperwork, and this will be sent out by Tuesday. I need to ask a question, because I don't want anything to cause any problems in this process. My wife wants to visit me in the middle of May, about 4 months after she went back to her home country of Spain. She is in between jobs and schooling...

Since the paperwork might not be received by USCIS before she arrives, and for that reason I wouldn't be getting the NOA1 confirmation of receipt wouldn't yet be issued, is there any possibility this could cause problems? I've heard there can be problems for filing the CR-1 paperwork when a spouse is in the US, as USCIS might think someone is intending to AOS without observing the proper procedure, this or anything that might be construed as such is something I want to avoid.

Thank you all for your input!
