Besides the work permit consideration mentioned by Vlad, I think you also need to make a case for why you are applying to the international office(s). Do you have past experience there? Have you ever lived there? Or any other legit personal reasons (e.g. family, partner)?
The office you apply to wants to know that if they get you in, you have some commitment to the firm/office. If you get in a total foreign office and realised it is not something for you and wants to leave in a short time, it is neither good for you nor for the company.
