Speculate away. She’s from Russia so a number of people are leading with that.
I’m trying to read up more on it and it looks like it maybe wasn’t denied but nothing has happened and it’s still pending. (This is as assumption). Appears she’s been waiting since February. Bizarre.
I recently worked in the US for 8 months and when applying for the job was told that the visa process now takes at least an extra month since the Trump administration came in but in the end it took about 2-3 months for me. If it’s almost 6 for her that’s insane and the fact she’s a high profile tennis player. Not a good look. Defending champion as well!
I think he has been busy doing other things rather than attending the US Open since 2016... If he wanted an invite to the tournament I don't think he'd have too much of a problem since most of the lower level boxes are owned by big business fat cats, which love him... And besides being busy as President of the United States, I don't think his ego could handle the negative response he would get from the crowd when he showed up. I was at the final in 2005, and when Bill O'Reiley was shown on the jumbotron, he was booed mercilessly, I'm sure it would be 10 times worse for President Trump.
What does illegal immigration has to do with work visas? Illegals do not seek work visas.
Visa overstays and illegal immigration are not the same
That is not illegal immigration that is visa overstays not the same.
Just kidding
I see your point but I think you probably meant people who come in on visit visas. The work visa (H1) requires sponsorship by an employer who has gotten labor approval etc from Dept of Labor, given job ads in classifieds to see other eligible US citizens don't qualify for that job etc, and the whole process is long and has a lot of red tape involved. A work visa holder can not get a professional job of that level since all employers do background and work eligibility checks etc. You can get your H1 transferred to another employer but once you are out of status, you can't get a professional level job without valid visa.
Kim Clijsters won the 2009 US Open.
Who POTUS is would probably not impact your trip. 
Whoops got her 2004 US Open title mixed up with her 2009 French Open title.
Why ? I don’t see Serbia listed:

Which type he wants you would have to ask Pepe but I would think he could get an O-1 Visa with no issues. I think for up to three years at a clip but call a local immigration lawyer, if you need one.
If you’re from the Soviet Union there seem to be some visa delays recently:

Some people probably think that she could influence the upcoming election
What the heck is "a non-immigrant visa refusal rate"?
