Personal care includes the right and at the same time the duty to care for, educate, supervise and determine the child's whereabouts. The child is a minor who has not yet reached the age of 18. Single is one who is not married and has not yet been; even those who live in a registered civil partnership are not single If these requirements are met, you must be granted a residence permit. You can also follow suit with your child if you do not have a personal care right. The prerequisite is that you already have a family life with your child in Germany. A family life is to be assumed if the relatives maintain regular contact with each other, which goes beyond mere visits. If the conditions are met, the authority decides by way of discretion on the granting of the residence permit. Under certain circumstances, the Immigration Office may oblige you to take part in an integration course. This will then be noted on your residence permit. The residence permit is a temporary residence permit and is issued for at least one year.
