You're asking a very vague question that is difficult to answer. The best data is in one of the NRMP data reports:
https://www.nrmp.org/wp-content/uploads/2022/07/Charting-Outcomes-IMG-2022_Final.pdf This one is focused on IMG's.
First, I assume you are a non-US IMG (i.e. you will need a visa here in the US). If I'm wrong about that, my apologies and the following will not be correct but you can get the correct data from the report.
In 2022, 62 non-US IMG's got an anesthesia spot and 85 did not - 42% got a spot. They had mean USMLE scores of 234/243 and 9 publications. 10% had PhD's. The data for Anesthesia starts on page 17 (page 22 of the PDF file)
No one can tell you what your chances really are. Will depend on your exam scores - which are very important, you need to study and do as well as you can on them, not just try to "pass" (although Step 1 is now Pass/Fail, so all you need to do is pass it). US clinical experience is highly valued and difficult to get. A visa definitely makes the process more difficult.
