1）在following to join申請綠卡的過程中， 海外配偶有沒有可能申請探親簽證赴美做短期探訪？
-Because of the immigration intent, your wife's B2 visa application may be denied. She may get the visa if she is lucky.
2）或者我太太持英國護照，原來可以免簽入境90天，但是在申請了following to join綠卡後，還能不能用免簽入境呢？
-Some issue as above comment. Of course, if she is lucky, she may be OK to enter US.
