1. 剛給哥哥一家申請移民，會影響哥哥和小侄女兒暑假申請探親簽證嗎？
-It should not because it takes more than 10 years for them to immigrate to US, but need to tell the truth during the visa application. By the way, the I-130 petition is only related to your brother, not the other family members. So, his kid will not be affected for the F-1 study (not need to report this I-130 petition during her B2 visa or F-1 visa application).
如果有影響，是否應該申請旅遊簽證，他們隻想來玩一個月
2.今後如果侄女有意向出來讀高中（那個時候綠卡還遙遙無期）， 申請F1來讀書可以嗎？-Yes. 會影響移民申請嗎？-No.
