My mother immigrated to the United States through investment two years ago and got a temporary green card for two years, but because she can hardly speak English, she was taken care of by the elderly.

1, month is the cycle of each departure. During this period, it violated the permanent residence law. 2, well, it all means a. 3, which means that your mother has done this many times and suggested canceling your mother's green card. If your mother keeps running back and forth like this, she will confiscate her green card and postpone it a little.

What you said, the immigration department thinks your mother understood the meaning of the endorsement on the passport. Because everyone who holds a green card knows the relevant departure regulations. That is, each departure shall not exceed 40 days. Otherwise, the Immigration Bureau can make green card holders voluntarily give up their permanent residence qualification on the grounds of long-term departure. Your mother has been warned three times.
