I’m against most adjectives and also against most uses of “nonviolent communication”, so let me offer a more fundamental reason to reduce your use of adjectives: It’s just clearer writing/speaking to omit them. And the attempt to write more clearly probably forces you to think more clearly. Precisely-chosen adjectives are fine, but “bad” conveys more noise than signal. The fact that it may hurt someone’s feelings is beside the point. You could just as easily offer a commentary on “AI 2027′s excellent timeline models” and “excellent” would be similarly uninformative. OTOH, a bare description of the facts will hurt an emotionally intelligent person’s feelings just as much as you calling it “bad”, because they get the point. Depending on context, it might even hurt more, because they know it’s a rationally-considered take and not an emotional one that you are likely to feel differently about once you calm down.
The focus should be on speaking/writing in a way that will most clearly convey meaning. “The kitchen is dirty” obfuscates; “the dishes need to be washed” makes clear what you want (and conveys just as much “judgment” to all but the most obtuse). “Your presentation was too dry”, OTOH, is better than “I didn’t like it”. But better still would be “I would like more examples of what these budget numbers mean for our day to day operations” or “expert consensus is that people will pay more attention if you sound excited when you give a presentation”.
I am skeptical of this. If you can’t afford to pay a lawyer, it’s unlikely your accomplishments would qualify you for anything you could self-petition for, especially under this Administration. In fact for some visa categories, commanding unusually high pay is literally one of the qualifying factors. And if your employer is petitioning for you then their lawyer should be helping resolve any challenges. I think EAs are less likely to delude themselves about this sort of thing than most people, but the risk is not zero.
There are exceptions, such as family-based petitions, where your salary history wouldn’t be relevant. But I would advise that this group should steer clear of anything like the extraordinary ability visa’s referenced in the post, because the nature of the group creates an adverse selection problem.
