不好意思偶比较愚钝。你是说回国探亲是可以的
Queston 1: "but the change of status should be considered as abandonment"
change of status --> 你是说从L2变H1B?
considered as abandonment --> a*****andonment of what? You mean abandonment of L2 status?
Question 2: 明白
Question 3: "The last entry before 10-1, you should get H1 visa stamp abroad and enter US to get a new and valid H1 I94." 你是说10月1日前探亲回来时要上美领馆重新签证H1B?
