Im in Canada. Found potential wife online in US. She is revert, niqabi, prays 5x. Parents are divorced and distant, partly cuz of reverting and other reasons. My mom is against it cuz of girl’s culture, family situation and hard to verify things. Should I go meet her and wali and marry if I like?

Ustadh AbdulAziz al-Haqqan
A parent's consent for the man is not a condition for marriage and he can get married without it, though winning them over is sought in either case. So, with good words, kindness, and dua to Allah, try to win her over, may Allah reward you.
