J2 and then F1

You should not be a resident for tax filing purposes for tax year 2024 since you were exempt holding a F1 Visa. 

According to the IRS:

"Do not count days for which you are an exempt individual. The term "exempt individual" does not refer to someone exempt from U.S. tax, but to anyone in the following categories:

• An individual temporarily present in the U.S. as a foreign government-related individual under an “A” or “G” visa, other than individuals holding “A-3” or “G-5” class visas.
• A teacher or trainee temporarily present in the U.S. under a "J" or "Q" visa, who substantially complies with the requirements of the visa.
• A student temporarily present in the U.S. under an "F," "J," "M," or "Q" visa, who substantially complies with the requirements of the visa.
• A professional athlete temporarily in the U.S. to compete in a charitable sports event."
