回複：請問兩個H1B的問題

1。聽說H1B簽證加延期一共可以有六年時間，可是當我在第一家公司工作兩年後，換到另一家公司，H1B轉換後有效期還是三年，這樣我還能再延三年嗎？
you can only exten one year after spended 5 years on H1 unless you satisfy the condition set forth on AC-21 memo.

2。持H1B簽證想回國探親，還沒開始申請綠卡，H1B也沒延過，回簽時容易嗎？有沒有可能被拒

H1 visa cannot be denied based on immigration intent. However, there is a risk of denying or delay if you ever changed status in US or if you work in a sensitive field.
