I can search various NMs, but this isn’t quite the same as USCF expert since it’s a different rating system and NM qualification varies country to country to my understanding. It would be more straight forward for me to see current USCF expert player profiles.
Are you a USCF expert?

A USCF expert is someone with a USCF rating of at least 2000 but less than 2200.
Right above that is USCF National Master which requires a 2200 rating.

Nice goal for one day
I'm not yet at expert level. I'm "only" USCF Class A (1800-1999) and I'm a lot closer to the 1800 side than the 1999 side xD Perhaps one day I'll cross that 2000 otb threshold and keep going higher; 2000+ rating is really tough to reach though and otb rating is even tougher than online.

Yes, although it should be mentioned that "expert" is a well-known category in USCF ratings, but not an "official title." It is more so an extension of the "Class" players to bridge the gap between them and "Masters" (titled players).

I was rated above 2100 USCF otb around 1990, but a 20+ year hiatus and old age have left me far short of that when I returned to the game after I retired.
Don't wait for your game to improve to play in tournaments. There are a lot of differences between online and otb, so playing in face-to-face tournaments will help your otb game more than playing exclusively online.
Experts in general are not tremendously more talented than most A-class players, but probably have better endgame technique and definitely know their favored opening lines more thoroughly. With some experience and a bit of study you should be able to achieve your goal.

Not there yet but have played quite a number of them and studied the Ratings between the two in a 200 player random sample. In that sample on average a uscf otb player had about a 150 to 200 pt higher chess.com rapid rating then their uscf rating making a good measure of where one's otb likely would be at arguably be to take one's rapid rating and subtract that much. Was true in about 55 percent of a case study I did, 15 percent had a chess.com rapid that was more then 50 but less then 150 pts higher than there uscf , 15 percent had chess.com rapids within 50 pts of their uscf and 15 percent had uscf ratings higher then their chess.com rapid ratings, but they were mostly older players or ones that didn't play rapid on here much I was noticing. would be interesting to do another sample and see if it got the same or different results. good luck on your quest for expert and 2000
My personal chess goal is to one day reach USCF expert. I haven’t played any tournaments yet, but I will once my rating here on chess.com reflects something similar to a typical expert.
If you are an expert, will you please comment here?
I want to explore experts’ rating ranges in various time formats, compare some of your games to my own, etc. Ultimately I’m just trying to get a better idea as to how far I have to go before my goal may be obtainable. Also, if you have surpassed expert already, it would be helpful to me still if you commented with the approximate date that you reached expert so I could look at that time period of your stats & game history.
thanks
