Yes, you can bring US dollars when studying abroad in 2025. According to Chinese regulations, individuals can carry foreign currency cash equivalent to up to **$5,000 USD (inclusive)** when exiting the country without declaring it. If the amount exceeds $5,000 USD, you need to apply for a "Foreign Exchange Carrying Certificate" from a bank or the State Administration of Foreign Exchange (SAFE) in advance and declare it at customs.
It’s advisable to check the latest policies with your local bank or SAFE before your trip, as regulations may be subject to minor adjustments. Always keep the certificate and relevant documentation handy for customs inspection.
