In order to get a visa, most countries require that your passport be valid for at least 6 months past your scheduled return to the U.S. If you are getting a multiple entry visa, and your passport is set to expire soon, you might consider getting your passport renewed first, since most visas in your passport are no longer valid once your passport has expired.

You may travel to the United States on a valid visa in an expired passport as long as all the biographic information on your visa (name, date of birth, nationality, etc.) matches the same information on your new passport. Ensure that the visa has not been hole-punched or damaged in any other way.

If you can keep your old passport with you, you do not need a new visa. Take the old passport with the valid visa and new passport together as your international ID.

The passport is valid for ten (10) years if you are 16 years of age or older. The passport is valid for five (5) years if you are 15 years of age or younger.

You may apply to have extra pages added to the passport. Alternatively if your passport will expire shortly you may apply to renew it. If you are a frequent traveler, you may request a 48-page passport in writing with your application. There is no additional fee for this service. Generally, citizens are allowed to carry only one valid passport at a time. In the situation described above, the issuance of a second passport is possible. Read more… .

You may continue to use that visa (provided it is not cut, cancelled or has expired) by carrying that old passport with your new one.

If the visa is still valid in the old passport, then there is no need for the applicant to apply for a fresh visa. Carry both the passports (the old as well as the new passport), and the applicant can travel to the U.S. using this valid visa.

Generally yes. If you have a valid U.S. visa in an expired passport, you may still travel to the U.S. on the valid visa, provided you travel with a valid passport of the same nationality as the expired passport and the two passports contain identical biographic data. For this purpose, both British National (Overseas) and Hong Kong SAR passports are considered the same nationality.

If your visa is in a passport that has expired, you will need to get a new passport before you can travel to the United States. You may travel with your old passport (with valid visa) and your new passport assuming that the visa is not damaged. If your personal data has been changed (for example you have changed your surname to reflect your married status) you have a choice to apply for a new visa in a new passport or travel with both passports and explain it to the immigartion officer at the U.

Visas in expired passports are still valid. Applicants may travel with a visa in an expired passport as long as their currently valid passport reflects the same biographical information and the visa in the expired passport has not been damaged.

No one may accompany a visa applicant to an interview unless the applicant is a minor incapable of communicating in any language spoken by the Embassy staff without the assistance of a certified interpreter, or in need of physical assistance for an obvious medical infirmity.

The length of time between the date you submit your application and the date on which your interview will be scheduled varies depending upon fluctuations in the number of visa applicants. We recommend you schedule your appointment approximately two-three weeks prior to your desired departure date. This will provide for unexpected surges in the number of applicants or other unplanned delays in the process.

The Consular Section strongly suggests that you apply well in advance of your intended travel date. While many visas are issued the day after the interview, certain applications require additional administrative processing, which can last, on average, between one (1) and four (4) weeks.

It is not possible to transfer a visa from one passport to another without making a new visa application.

The applicant must carry a Police report (FIR), filed at the police station closest to the crime scene and a photocopy of his lost passport showing the valid U.S. visa. You are strongly recommended to keep photocopies of your passport's data pages and of the US visa. A US non-immigrant visa is a valuable document. Inform the US Embassy/Consulate from where your visa was issued immediately if you have lost your passport. You would need to obtain a new non-immigrant visa.

All visas are now placed inside your passport. They function exactly the same as the older border crossing cards, which are no longer issued at the U.S. Embassy. If the passport expires before the visa, you must travel with two passports (your current passport and the expired passport with the valid visa inside).

The U.S. Consulate General in Hong Kong returns all nonimmigrant and immigrant visas to successful applicants by Hongkong Post. Delivery usually takes two to four days. However, individual issuance times may vary significantly. You should apply as far in advance of your planned travel date as possible.
