Consulting an attorney is not a bad thing at all. However, here it is clear I am right and you are flat out wrong. Dozens thousands people apply for nonimmigrant visas every year while in the GC process (H-1, L-1 and some other visas as well), and dozens thousands people enter US on nonimmigrant visas while in the GC process (when they enter US with those visas). That is very much common, significant percentage of nonimmigrants is supposed to do that and does that.
I analyzed you arguments. You make a statement, then I prove it is wrong.
It happened three times. Your statements were:
1. Entering on a nonimmigrant visa while having an immigrant intent is fraud.
2. Not voluneering information is misrepresentation.
3. Truthfully filling out a nonimmigrant visa application while having an immigrant intent is fraud.
All three statements contradict to existing US laws, and references were provided.
