是关于h1b返签,那个DS156表上,我有好几个问题,不知道该怎么添

如果有人知道的话,多谢回答

关于26，
name and telephone numbers of person in us who you will be staying with or
visiting for tourism or business?

这个是填我现在manager的名字吗？

30， have you ever been issued a u.s. visa?
我刚从f1转成h1，我是不是两种visa都要填阿


36。 has anyone ever filed an immigrant visa petition on your behalf？
公司律师帮我申请h1，这个算是吗？
