Device & OS

Scenario
Trying to open a fillable government PDF form directly within a web browser.
Observed behavior
The browser's built-in PDF viewer fails to load the form content, instead displaying a 'Please wait...' message indicating compatibility issues.
Before you start

Ensure you have a dedicated desktop PDF reader installed on your computer, as browser-based PDF viewers lack the necessary support to render dynamic government forms.

Solution 1Recommended

Download and Open the I-9 Form in a Desktop PDF Reader

Saving the file to your local computer and opening it with a dedicated PDF application bypasses the browser's limitations.

Many official government forms, including the USCIS I-9, are created using advanced XFA (XML Forms Architecture). Standard web browsers like Chrome, Edge, and Safari do not support these dynamic scripts, which triggers the 'Please wait' fallback message.

To properly view and fill out the form, you must download the file locally and use a standalone PDF reader.

1
Download the PDF file

Right-click the I-9 form link on the USCIS website and select 'Save link as...' or click the download icon in the top right corner if you are currently viewing the error page.

2
Choose a save location

Select an easily accessible folder on your computer, such as your Desktop or Downloads folder, and click 'Save'.

3
Open with a dedicated PDF reader

Navigate to the saved file, right-click on it, select 'Open with', and choose your installed desktop PDF application (such as Adobe Acrobat Reader or WPS PDF).

Avoid double-clicking the file: If your computer's default PDF viewer is still set to your web browser, double-clicking the file will simply open it in the browser again, causing the same error. Always use the 'Open with' right-click option.

Frequently Asked Questions

Why do government PDFs say 'Please wait...'?

These forms are often created using dynamic XFA formats to accommodate interactive elements and barcodes. Built-in browser PDF viewers cannot execute the scripts required to render XFA forms, so they display a default 'Please wait...' compatibility message instead.

Can I fill out the I-9 form on my mobile phone?

Mobile PDF viewers typically lack the required support for dynamic XFA forms. It is highly recommended to download and complete the I-9 form using a desktop or laptop computer with a dedicated PDF reader.

How do I stop PDFs from opening in my web browser automatically?

On Windows, right-click any PDF file on your computer, select 'Properties', click 'Change' next to the 'Opens with' option, and select your preferred desktop PDF reader from the list to set it as the new default.

Will I lose my entered data if I close the form?

If you fill out a PDF within a browser environment or without properly saving it to your local drive first, you risk losing your inputted data. Always download the file to your computer and open it in a desktop PDF application before you start typing.
