My personal experience tells me that "like you are" is even more polite and more emphatic.
You should have in mind that using either "like you" or "like yourself" may unintentionally offend people. With regards to P.E. Dant's comments I think he has a point in that people may not see themselves as foreigners, especially within their homeland.
To avoid offending somebody I recommend you change "foreigners" to either "people" or "non-native speakers" and possibly use a positive qualifier:
- My first name may be difficult to pronounce for good (or whatever other qualifier) people like you/yourself/you are.
You could add "even" too smooth the phrase even more:
- My first name may be difficult to pronounce even for such good (or whatever other qualifier) people like you/yourself/you are.
Or maybe something like this:
- My first name may be difficult to pronounce (even) for people who are as good/clever/educated/well-educated/intelligent/literate/well read/intellectual/sophisticated as you/yourself/you are.
