> The law does have immigrant visas for people who can come here and say "I want to work here and seek permanent residency. I'm not intending to go back." H1B isn't like that.

you are, obviously, interpreting the law to fit your narrative:

""The fact that an alien is the beneficiary of an application for a preference status filed under section 1154 of this title or has otherwise sought permanent residence in the United States shall not constitute evidence of an intention to abandon a foreign residence for purposes of obtaining a visa as a nonimmigrant described in subparagraph (H)(i)(b) or (c), (L), or (V) of section 1101(a)(15) of this title or otherwise obtaining or maintaining the status of a nonimmigrant described in such subparagraph"

All this means is that you, indeed, can be dual intent and apply for permanent residency while holding a H-1B, like generations of Americans have done before ourselves.
