You can apply for U.S. citizenship after 5 years (3 years if you’re married to a U.S. citizen).
You may sponsor certain relatives for visas or green cards.
A green card enables you to travel in and out of the U.S. more easily.
You can simply renew a green card every 10 years.
A green card makes you eligible to make financial contributions to U.S. Elections, which means you can support candidates that will make your life easier or that you otherwise agree with.
The Cons of Having a Green Card
When you are a legal resident of the US, you are required to report your worldwide income earned during the tax year on your US Federal Tax Return, not just your US-sourced income.
If you are a male between the ages of 18 and 25, you must register for the US Selective Service.
It is possible to lose your green card if:
* You are absent from the country for longer than a year without filing for a re-entry pass
* You commit a felony - even a minor one
* You fail to notify the USCIS about a change of address
* You help an illegal immigrant enter the country
* You engage in a false marriage
Even though green card holders can make financial contributions to US elections, they cannot vote or become elected officials.
