Need Advice - USA perm resident travel back to Thailand

I went through the same situation with my Thai wife.

The advice I see posted is good.

My wife and I live in Thailand now.

Did you know that if your wife leaves the US for more than 12 months she will lose her permanent resident status?

Even though my wife was only 6 years into her 10 year visa, she lost the status when she couldn't return before the 12 month date due to an illness.

Now to return to the states we would need to go through the entire visa process again.

The first time took almost 3 years for approval.

I debate weather it is worth returning or not.

Choke Dee!

At one time there was no limit.

But it is possible to file paperwork to prevent loosing it.

A stay out of the US of more than 6 month requires a re-entry permit that costs about $150.

Is this a relatively firm rule? Or is it at the discretion of the agent at the US port of entry?

Are there any guidelines available for how many months per a Thai citizen must stay in the US to maintain permanent residency status. The reason I am asking is that we would like to stay in Thailand more than half of the year. It seems that my Thai fiancee (soon to be wife) would have a problem getting a tourist visa to the USA for 3-6 months per year as she does not now have a job and no longer ownes property in Thailand.

Thanks
