In a nutshell, yes I could see adcoms jumping to conclusions based upon traditional career roles, goals and how they align with the typical profile of an international student. This is why the best strategy is to address such concerns head-on. Not that you would use the following language, but the message should be some version of: I realize there may be concerns about an international student trying to get a traditional job with P&G in marketing, however this is why it's going to work for me....
then you lay out your case for how your approach is different and will not result in any problems landing the job. When you attack concerns head on, you remove the ability of the adcom to make their own assesment and essentially innoculate the concern ("nip it in the bud") so to speak. Now, of course just the fact that you identify their concern will not get you there--your logic and your plan must be believable and achieveable. In other words, you must achieve the classic goal of all applicants: sway the committee into your camp with compelling arguments and interesting evidence for admission. good luck!
