Does "Apply for scholarships, get accepted and then refuse" help in your CV? I have a situation. I want to apply for Ph.D programs in the United States at the end of this year. And right now, there are many programs in Europe open for application. Hence, I wonder if I should try to apply to them, get accepted and then refuse the scholarships.

Is it ethical? I am worried that it could affect my reputation and my LoR would no longer be appreciated in the future, leading to mistrust in my lecturers who wrote my LoR. On the other hand, getting accepted may prove my competence and prowess.

If the answer is yes, should I put it in my CV for future application?

Thank you for your help
Do not do this.

Programs in the US generally do not care if you've been offered admission to programs in other countries. You are judged on your aptitude for research and to make future contributions in your field. If you cannot convince an admissions committee this between your record, your statement of purpose and personal statements, and your letters of recommendation, then how will you get an offer in Europe—when generally the same materials are needed to get you through the process?
