If a parent wishes to apply for Turkish citizenship through investment, the application can be expanded to include minor children as well. However, in your case, if you will apply for Turkish citizenship based on your marriage to a Turkish citizen, your children from another marriage will not benefit and will not be able to obtain Turkish citizenship through you. You could still use the investment option rather than marriage and include your minor children without Turkish citizenship in your application; however, the father of those children would still need to approve.
