You will need to use a VPN, or a DNS service like Smart DNS. Many VPN providers have US based servers for watching Netflix and other US steaming services. However you can use Netflix without doing this and you will be able to watch the local Netflix, as your Netflix account works world wide.
Note that when just connecting to a regular US server, most likely Netflix, Hulu and some other streaming services, will recognise that you are using a VPN and won't let you access the US Netflix. Some streaming services like Sling, can be watched from any US server.
It pays to have a look at recent customer reviews form VPNs, as sometimes the servers for Netflix, stop working. Hopefully recent reviews will be able to tell you if these servers are still working.
