Can supporting documents be submitted on A4 or letter size paper?

Yes. In practice, for an EB-2 NIW petition, both A4 and letter formats are generally accepted. The USCIS does not typically require exclusive use of one size over the other.

What truly matters is not the paper size, but rather the organization and readability of the overall package. If your documents were printed on A4, there is no need to convert them to letter, and vice versa, as long as the formatting does not hinder readability.

• Keep documents ordered and easy to follow.
• Make sure nothing is cut off or illegible in print or scanned form.
• Use certified translations when a document is not in English.

That said, formatting requirements can change over time. It is always worth checking the latest guidance from USCIS before assembling your package, or confirming with a trusted specialist, and avoiding services that promise guaranteed outcomes.
