Will my medical bills affect my kids’ citizenship as they have their passport renewal in 2018?

If you have a green card and do not renew it when it expires, you can lose your permanent resident status. But citizenship is not lost if you do not renew your passport. In fact, many Americans never get a passport in their lives as it is needed only if the person wants to travel abroad. Your children were born on the U.S. soil and became U.S. citizens with their first breaths. It does not matter if you will or will not renew their passports: their birth certificates are the proof of their citizenship, and they can obtain new passports any time. They also do not need to come to the U.S. to renew their passports: they can apply for new passports at the U.S. consulate or Embassy in your country. Your use of Medicaid also does not affect your children's citizenship and their ability to come to the U.S. any time they wish to do so. You, however, might want to make an effort to clear your debts. Write to the hospitals where your children were born, ask them for statements of any payments due. If you receive invoices, try to pay them or retain an attorney to negotiate a settlement (most hospitals will accept a partial payment to settle the account). But it is likely that the hospital will reply that they do not have records of your outstanding debt or that it was written off. Either way, you will have something to show the consul the next time you apply for a visa.
