Don't do it!!
My wife was denied entry to US because of an 8 hour ESTA overstay, caused by COVID and flight cancellations in 2020. We got married soon after this, and applied for both the CR-1 and a B-2 visas. At the 1st B2 appointment in Vienna, she was denied without any reason given, only "you can reapply...". We had a second interview a month later, denied again. The officer implied that the CR-1 application was a problem for the NI visa, but didn't say it directly. After many emails with Frankfurt and NVC staff, they basically said you cannot apply for both IV and NIV at the same time.
I wish this would have been clear at the beginning. We would have not applied for the CR-1 until we had the B-2. My wife has not been able to visit our US home for almost 2 years because of a nasty immigration agent at Houston.
