If you wish to obtain J-1 exchange teacher status, you must maintain adequate health insurance throughout your entire stay in the U.S.  Failure to do so may render the teacher out of status, requiring you to be removed from the exchange program and return to your home country immediately.

HEALTH INSURANCE REQUIREMENTS FOR J-1 AND J-2 EXCHANGE VISITORS (EVs) Pursuant to 22 CFR Part 62.14, adequate Health Insurance coverage is mandatory for EVs and their dependents for the duration of the program. Specific minimum coverage provisions for your health insurance policy while in the US must include:

(1)  medical benefits of at least $100,000 per accident or illness;

(2)  repatriation of remains in the amount of $7,500;

(3)  expenses associated with medical evacuation of the exchange visitor to his or her home country in the amount of $10,000; and

(4)  a deductible not to exceed $500.

Medical insurance must be maintained throughout your entire Exchange Visitor Program, in advance, for the whole school year.  Failure to maintain the above health insurance minimums will render the EV out of status and constitutes grounds for removal from the program.
