Is it permissible to postpone conception and promise that to the father temporarily - until one finishes studying and finds a job - in order to confront the fear of falling into immorality, given that marriage is necessary for psychological illness, and due to the current difficult financial circumstances?

Delaying childbearing until the completion of studies and obtaining a job is permissible, but it is contrary to what is better. Perfection and virtue lie in reliance on Allah and trusting in His guarantee of provision, which does not contradict reliance. Therefore, it is advisable to hasten marriage and not delay childbearing, out of trust and reliance on Allah, knowing that childbearing is a right of both spouses, and withdrawal (coitus interruptus) is not permissible without the wife's permission.
