H1B回国首签 - FAQs - 求有经验者告知

就，看dhs的解释呗
Can a nonimmigrant in H-1B or L-1 status intend to immigrate permanently to the U.S.?

Nonimmigrants in H-1B or L-1 status can be the beneficiary of an immigrant visa petition, apply for adjustment of status, or take other steps toward Lawful
Permanent Resident status without affecting their status. This is known as "dual intent" and has been recognized in immigration law since passage of the
Immigration Act of 1990. During the time that the application for LPR status is pending, a nonimmigrant in valid H-1B or L-1 status may travel on his or her
visa rather than obtaining advance parole or requesting other advance permission from USCIS to return to the U.S.

所以4/5/6这三个问题有什么关系呢

以上问题都没有答案😓 但是有一个我觉得要注意的就是简历不要写得太复杂 能多简单就多简单 让面试官一眼就看懂 别给他因为搞不懂简历上的专业词而check你的机会
