Exactly. It's discretionary, but for reasons I won't go into here, I had to have an immigration attorney for my green card adjustment. Her constant refrain was that I was not to worry as it was "discretionary but presumptive" - my previous efforts and process laid it that the onus was on the USG to show that my green card was or might be fraudulent or in bad faith.

Now? The same applies, but the current administration's attitude is "So stop us."

My friend was married to a USC (bona fide legit marriage) and they almost fucked them over during Biden administration casting doubt on their marriage. In San Francisco, not some red state. Many examples of that nature regardless of the administration.

Almost always if your case is legit, you'll be fine in the end and nothing to worry about, just as your lawyer says, but it does not mean there won't be a bumpy ride. I genuinely doubt Trump administration is any worse or better unless you affirmatively have anti-Western ideas or from Travel Ban countries. In fact, the anecdotes I have heard so far on the consular processing of Immigrant Visas is better than Biden era.
