> But to get a new physical stamp, I have to re-enter the country every 3 years. How does that make sense?

Why do you need a new physical stamp at all if you are not re-entering? I think your argument is backwards here. What I think you’re asking is “why can I stay in the country without taking this step, but I have to take this step to re-enter.”

Well, because when you leave the country you are subject to certain laws. Even a permanent resident cannot just leave and expect to come back whenever without consequence. Even a person eligible to apply for citizenship must meet a minimum threshold of presence.

Now, your question becomes “why are the laws the way they are” and/or “why doesn’t the law make sense”. I conjecture that these situations are particularly fringe for our legislators so they don’t get a ton of attention, and they make just enough sense to remain as is.

Visa is valid for 6y, entry visa for 3. You decide to visit Europe in year 4, you have to travel to southeast Asia or South America to renew your entry visa before you can get back to work? Sounds stupid.

Another incredibly stupid thing of the American system is the fact that your spouse cannot work while you're subject to it.

No, you can get your new visa in any country US consular services are in, not just your home country.
