- Device & OS
- not provided
- Scenario
- Trying to access and save an official government PDF form from a browser.
- Observed behavior
- The PDF form fails to download or fails to open correctly within the browser tab.
Ensure you have a stable internet connection and are using a desktop or laptop computer, as complex government PDF forms often encounter compatibility issues on mobile devices.
Save the PDF Directly from the Browser
Instead of clicking the link to open the PDF in the browser, force the browser to download the file directly to your computer.
Most browsers will try to open PDF files in a new tab by default. However, complex government forms like IMM 5644 contain dynamic features that standard browser PDF viewers cannot process, which makes the download appear to fail or display an error message.
Navigate to the official Government of Canada website. Instead of left-clicking the IMM 5644 link, right-click on it to open the context menu.
Choose 'Save link as' (Chrome/Edge) or 'Save target as' from the dropdown menu to initiate a direct download.
Select a location on your computer, such as your Desktop or Downloads folder, to save the file and click 'Save'.
Locate the saved file on your computer and open it using a dedicated desktop PDF reader rather than your web browser.

Clear Browser Cache and Disable Extensions
If the download still fails, browser caches or interfering extensions might be blocking the PDF download.
Use an Alternative Supported Browser
Some web browsers may have built-in handlers that fail to process complex file requests properly.

Frequently Asked Questions
Why do I get a 'Please wait' message when opening the IMM 5644 form?
This message appears when you try to open a dynamic XFA PDF form in a web browser that doesn't support it. You must download the file to your computer and open it with a dedicated desktop PDF reader like WPS Office or Adobe Acrobat.
Can I fill out the IMM 5644 form on my smartphone?
It is highly recommended to use a desktop or laptop computer. Mobile browsers and basic mobile PDF viewers often do not support the complex formatting and interactive fields required by official Canadian government forms.
What should I do if the form says it needs an update to the latest PDF viewer?
This indicates the software you are using cannot process the dynamic content of the form. Save the PDF locally and open it with a fully featured PDF reader that supports advanced forms, ensuring your software is updated to the latest version.
