work from anywhere but appear like I'm working from the US

I work from home. I have a work computer that I don't have any admin rights on. I use Cisco anyconnect to connect to my work VPN. I am looking for a networking and security specialist to JUST right me a plan on what to do. no actual networking or remote work required. what I need to be able to do is: Take my laptop to Canada for example, and carry another laptop or a slim desktop with me that will have a wifi or wired network setup that I can connect to with my work laptop and when I connect to my work VPN, it will appear as if I am connecting from the US. I would like the solution to include an internet source from cable modem "or" from 4G/LTE network as a source of internet.
