My green card holder mother in law applied for my husband's immigration before our marriage. After getting married he informed NVC with my papers to include me, but his immigration got canceled. Does that make me derivative immigrant? I am applying for f1 visa and I need to answer if anyone applied for my immigration. What should be the answer?

You answer yes, of course, he applied for you. It doesn't matter who got cancelled.

Thanks for your answer. Please add information that my husband was not an immigrant his application was still under process when he changed his status. Thanks again

Sorry can't add any information regarding immigratiion status, we are not a government subsidiary. You will have to consult with the immigration office from whatever country you are applying to.
