Taxes

My wife who’s a US citizen has not been working since 2020 and was not filling taxes. She only officially started working this year. I’m on F1 visa but I’ve been filing taxes since 2022 and I have all my tax documents . We’ve been married for almost two years now but we’ve not filed for any adjustment of status yet as I told her I want to complete my college first and weigh my options of staying here or going back to my home country. In the circumstance where we finally plan to file , what do we do about her taxes ? Of course we will get financial sponsors when we are ready to file. But I just want to know what do we do?
