If you are a non-US national who legally resides in United States as either a Permanent Resident, or valid US visa holder, we can assist with travel outside of US requiring a visa.
In almost all cases, your physical passport is required by the consular office at the time the visa application is made. The visa itself will be stamped or applied to a page in your physical passport book. The exception to this rule is the eVisa process. For an eVisa, Washington Express Visas will use a scan of your passport instead of the hard-copy document.
The pages in the back of a US passport are used for Amendments and Endorsements made to the passport by the US Dept. of State only, and foreign countries will not place visas on pages marked as such. Pages available for visa issuance by foreign countries say ‘Visa’ on the top of each page.
