Merry Christmas and happy new year. It's been a tough year with stress about work, immigration, family. This little corner of the internet always gives me joy, hope, and inspiration to work for a better, kinder world.

Hope everyone enjoy the break and start 2026 with energy to keep improving yourself and the world.

We are married so are there steps we can take to decrease the chance of them "connect" her to me? Should we avoid crossing the border together?
Hello, I'm currently on an H1B waiting on my priority date (I'm Canadian but born in China), my H1B hits the 6 year mark next year. My wife is currently on a TN which expires next year.

Should she switch to H4 EAD under my H1B instead of renewing her TN?

I saw the post on using AWS to play games too. Used it to play the division for a while. Glad to see a service being built for this.

Signed up and will be trying it out this weekend.

Re:Sorry, Chicago but Peter Thiel Is Mostly Right on Tuesday September 20, 2016 @08:41PM (#12544556)
Toronto is certainly growing and certainly the most ambitious and challenging city in Canada. However it's not near the level of Bay Area or even NYC for tech. There's a small community that you can be a part of but the general feeling of energy isn't there.
Hey, don't be too hard on your self. I failed interviews from Big 4 and a lot of other startups too. There are tons of false negatives as a part of the interview process.

Just focus on yourself and your job.

If you switch jobs you'll have to apply to a new TN visa at the border.

Fellow Canadian that's been in the USA for the past 4 years.

Hi Peter,

My wife and I are Canadians working in California on TN visas. I'm at a small startup that doesn't sponsor H1-B but I might start my own business in the future. Should I look switching to a larger company in order to get H1-B so I have the freedom start my company?

Thanks for doing this AMA.

It was a big surprise to receive that in the mail. Wasn't sure if it was a joke or serious but after looking for it on Google maps I think I have a future trip planned.

it is for me and i hate it. It's as annoying as when facebook added the right side events bar and throw the news feed off center.
