Is it permissible for a woman to work for a sister in faith and earn money from her work to be able to perform Hajj and help her parents, and is it permissible for her to perform Hajj with her grandfather and maternal uncle while she is unmarried, or is it better for her to wait to perform Hajj with her future husband?

A woman's covering of her face and entire body is a religious obligation. Studying in mixed-gender schools is not permissible. Working for a wage is permissible (halal (definition)) and is better than begging. If a woman has the financial means for Hajj and a mahram (definition), she must perform Hajj immediately without delay to await marriage, as marriage is not a condition for Hajj.
