Just so you know, the regulations in the US exist for a reason, and most US medical professionals will not be impressed by (read: may frown upon) people taking advantage of the 'much less stricter' standards abroad in order to get hands on experience that they are not qualified for. I would be more concerned about that than the scribe manager's opinion on the matter.
To answer your question: your scribe manager is trying to fill their shifts. They are generally flexible and willing to work around schedules, interviews, etc., but no employer is going to be thrilled at the idea of hiring someone and then immediately giving them a month's worth of vacation before they've worked there even a year. Hell, some places frown upon using your officially-given 2wks in one huge block, or using all of it prior to your 6-month mark...so yeah, if the manager hears your plan and has other hiring prospects, you'll be at a disadvantage. They understand your perspective, sure, but you should also understand theirs, and that your desire for diverse experiences doesn't obligate them to cater to it when there are other students that are a better fit for the company's needs.
Honestly I would advise against compromising an opportunity to gain long-term, valuable exposure to US medicine (more likely to be relevant to your future career) in exchange for a short period of exposure to foreign medicine that you may or may not be able to discuss fully in your applications without raising eyebrows (if you choose to take advantage of the more lax foreign regulations.) If you work as a scribe and you are proactive, odds are you will get to know US surgeons and get US shadowing opportunities to observe in the OR. You will certainly witness countless procedures in the ER (and learn how to document them. I would weigh the costs/benefits of the two carefully. Right now you seem to be leaning towards what sounds flashy to a premed, rather than what will actually help and inform you in the long term as you work towards your US medical career. Adcoms are more likely looking for the latter.
