That could be tricky. You can't deduct (as a work expense), training needed to meet the minimum requirements for your job or to qualify for a new job, but you can deduct training that extends or improves your skills in your current job. So you would have to look at this training on that basis.

Then, international travel is allowed, but you need to be careful that you only deduct expenses related to training and not expenses related to personal travel (i.e. vacation). There are a series of rules and tests in publication 463. https://www.irs.gov/forms-pubs/about-publication-463
If the travel is "entirely for business" (based on 4 tests that are described in the publication) then you can deduct transportation, 50% of meals, and your tuition or registration expenses. If the travel is not "entirely for business" (and therefore partly personal) then you can only deduct the registration fees and other expenses that are directly associated with the training.
