Eligible insured students may also purchase dependent coverage. Dependents must be enrolled on the date the student is enrolled or within 31 days of birth, marriage, or arrival in the U.S. An Eligible Dependent may be the Eligible Participant’s lawful spouse and/or his/her unmarried children under age 19 who are chiefly dependent upon the Eligible Participant for support and maintenance. The term “child/children” includes a natural child, a legally adopted child, a stepchild, and a child who is dependent on the Eligible Participant during any waiting period prior to finalization of the child’s adoption. The Eligible Dependent is one who has a similar visa or passport accompanies the Eligible Participant while that person is engaged in international educational activities; and is temporarily located outside the Eligible Participant’s Home Country as a non resident alien. Dependents of an Eligible Participant mush possess a valid passport and a proper visa (F-2, J-2, M-2). A “newborn” will automatically be covered for Injury or Sickness from birth until 31 days old, provided that the student is covered under the plan. Coverage may be continued for that child when the Company is notified in writing within 31 days from the date of birth and additional premium has been paid.
