The Visa Sponsor is also responsible for issuing an IAP-66 to bring your spouse or children to the United States. We will always review your financial sponsorship, and sometimes consult with your Financial Sponsor before issuing the requested IAP-66 for permission. In many cases, we are acting as the advisor on behalf of your Financial Sponsor. In every case, if you have questions, make an appointment with an advisor before taking steps that might effect your visa. It is a very important document.
Most passports are good for a limited period of time.
You can apply for extension of your stay in the United States or for various permissions as long as your passport is valid. However, if your passport will expire soon, you must send it to the Embas sy of your country for renewal. It usually takes several weeks for a passport to be renewed, so be sure to allow enough time. The ISFS Office has the addresses and phone numbers of embassies and consulates to which you will send your passport for renewal. Occasionally they are issued under other circumstances.
