Can I use my old passport number if it's expired?

No. Embassies require valid passport numbers. Using an expired passport number will result in visa rejection and lost fees.

Will my visa be valid if I get a new passport after approval?

Most visas remain valid when you get a new passport, but you must carry both passports when traveling. Some countries require visa transfer to the new passport for a small fee.

Can I apply for multiple visas once my new passport arrives?

Generally yes, but some countries require the physical passport during processing, so you can only apply to one at a time. Research each country's requirements before planning multiple applications.

What if my travel date is in 2 weeks and I don't have my passport?

Contact your country's passport office for emergency processing if available. Some countries offer same-day emergency passports for urgent travel. This typically costs $200-400 extra but may be your only option.

How to apply for visas when you don't have your new passport number yet

Most countries won't accept visa applications without a valid passport number, but you can prepare everything else while waiting. Apply for expedited passport processing if urgent, or consider if you truly need the visa before your new passport arrives.

Check if you actually need the visa before your new passport. Look at your travel dates and visa processing times. If you're traveling more than 3-4 months from now, you probably have time to get your passport first, then apply for the visa.
Expedite your passport if time is tight. Pay for expedited processing (2-3 weeks in the US for $60 extra) or emergency processing (8 business days for $17.56 extra). This is usually faster and cheaper than dealing with visa complications later.
Prepare all other visa documents while waiting. Gather bank statements, photos, invitation letters, flight bookings, and hotel reservations. Complete application forms except for passport details. This saves weeks once your passport arrives.
Contact the embassy if you must apply immediately. Call the embassy's visa section directly. Some countries (like India for certain visa types) may accept applications with your old passport number plus proof of renewal application. This is rare and country-specific.
Book refundable travel arrangements. Make refundable flight and hotel bookings using your best estimate of travel dates. You'll need these for most visa applications, and you can adjust dates once you have timeline clarity.
Apply immediately once your new passport arrives. Submit your visa application the day you receive your new passport. You'll have all other documents ready, so this takes 15-30 minutes instead of weeks of preparation.
