Question regarding dependents for 2025 tax year

I recently got married to my fiancée from another country. I brought her to the US on a K-1 visa. From my understanding, I should file jointly with her as a married couple. What I can’t seem to figure out is if I should claim her daughters, now my step daughters, as dependents. I found that you should claim a dependent if they lived with you for more than 6 months and you provided more than half their financial support. They arrived in the US in September, however, I was lucky enough to be allowed to work remotely, out of their country, in April. From April-August I was living with them in their home country. Would this time outside of the US count towards the 6 months, meaning I should claim them as dependents? Or would I only file jointly with my spouse?
