H1-B transfer到新公司 - 薪水

My company decided to sent me to Germany for more than 1 year and I just filed PERM...

Would you please share me what's the frequency to come back in US and stay for how long is safe to enter US?

Thank you !

※ 引述《chiahuay (harry)》之銘言：
: 我目前是under H1-B visa,請問一下,
: 如果現在換工作,H1-B transfer有何限制?
: 譬如:前後position或是title是否要差不多?
: 或是新工作的薪水至少不能比前一份工作低太多?
