Having Trouble Importing Foreign Employees using IIF file

There isn't a way import or manually record these addresses.

QuickBooks does not support foreign addresses for employees.

Thanks for visiting the Community for your IIF file concern, @tmartinez.

I'd like to ensure you'll get routed to the right direction to help you in getting rid of the error that you received when importing the IIF file.

To give you the resolution on what's the right thing to do in fixing the error 3110 that you received, I suggest reaching out to our Intuit Developer. This team is the best resource for such inquiries as they are the experts when it comes to qbXML status code for IIF files.

You can reach their forum through this link: Intuit Developer.

On the other hand, QuickBooks doesn't allow you to enter an address outside the United States to show in their W-2 form. 

As a workaround, you may consider pulling up the W-2 form, then manually enter or override the home address of the workers from Mexico.

To do that:

1. Go to the Employees menu at the top, then select Payroll Center.              
2. In the File Forms section, hit on Annual Form W-2/W-3.
3. Click on Create Form.
4. Select the appropriate employees, then choose the filing period and click OK.
5. In the Payroll Tax Form, click Next until you reach the Form W-2 Worksheet page.
6. From the Employee's address and Zip code section, right-click the address, then select Override.
7. Enter the home address of your employee, then select Next once done.

You can always visit this IRS article and refer to page 15 for the employee's name and address in W-2: https://www.irs.gov/pub/irs-pdf/iw2w3.pdf.
