但在准备485时，因涉及我而遇到一个头疼的问题。
我曾于08年持J1来美作访问学者一年，08年底回国（有两年的服务要求）。在近三年的时间里，断断续续
多次来美探亲（现在在美国，是H4身份，打算明年一月底回国）。算了一下，J1后在国内才待了一年半的
-If evey time you visit US you stay was too long (e.g. > 2 months continuously), you might not be counted as the home resident entirely. You need to get the J1 waiver before you file I-485.
想请教一下：
1 如果我和老婆现在一起交485，会不会因我的服务年限不够而被拒？
-Yes.
2 如果这次单独交她的485，在她取得绿卡后，如何为我办理绿卡？需要多长时间？
-If you get the J1 waiver or meet the two year home resident requirement, you can file I-485 within US diectly (if you are in US) which may take several months or aftr yoiu wife gets her GC, she can files I-824 for you to apply for the immigration visa in the US Consulate in Guangzhou which may take 6 months to one year for entire process.
在此期间我还能否来美？以何身份？何种签证？
-Techincally, you still can apply for a visa such as B1/B2 to enter US, but it may be somewhat difficult than H4 visa.
3 140批准后，能否等到我下次来美（比如明年8月，凑够两年服务期）后，再一起交485？
-Yes. Doable.
我想她不交485，就可以保留H1，我仍然可以申请H4来美。
-Doable.
这两种方法哪种更好些？
-Up to you.
