My impression is that US customs officials are either quite knowledgeable or quite tolerant on such issues (or a mixture of both). The same applies to customs officials in other countries I have traveled to, and other people at airports and such.
Thanks. (And, I don't have the knowledge to agree or disagree.)
I can't resist mentioning the case of Edward Snowden's middle name in Hong Kong :-) The issue there was a different one from what I am asking about, though, and you never know whether such things actually make a difference.
But in general, trying to figure things out and then being consistent will be good advice.
