hadron, did you yourself go away for two years - without your spouse and/or your children, and spend the two years without separation problems?
I didn't say separating from your family. When I got married, this was in the understanding that we might or might not have to move to another country (possibly a third country like the UK) for a couple of years before returning to the US. I got my waiver and everything worked out fine, but this was part of the deal with my wife from day one. My sister in law married a J1, from day one it was clear that this is what he signed up for and that they would have to adhere to the conditions of his visa.
I don't know where the OP is from, but unless his home country is ravaged by civil war (which could have gotten him a persecution waiver) or a really dark place where his wife will have to wear a bee-keepers suit and get her hand chopped off for driving a car, there are certainly options to go back. There might be no star-bucks and they don't have rounded door-knobs, but heck give me a break here.
Did you, maybe, have a medical condition that is not treatable in your own country and have to suffer for two miserable years?
If that was the case, there would certainly be grounds for a hardship waiver. The OP didn't mention that. The pure fact that your spouse would have to live abroad for 2 years is not a hardship in their book (and in my either).
As for the 'no objection' waiver: His country funded him to go abroad IN ORDER TO COME BACK and apply his skills for the benefit of their economy and research institutions. So, they do have a very good case to require his return. (Where I come from, the goverment will still give you the no-objection statement because they know that their ex-pats in the US research machine are a very valuable asset, but it is certainly up to individual countries to set their policies).
if not, I don't think you should tell people it's better for them to go back for two years. Coz it's not.
Please read my post, it started with the word 'Sometimes', which would infer that in many OTHER cases going back is NOT the better option.
I just see people struggling through lots of anxiety to get their various changes of status approved and then sit for years on AOS with EAD renewals annd interviews and 6hr trips to the local office etc while they could already be on their way to citizenship if they had gone abroad for the 2 years.
Sometimes, it's not so much about a freshly minted visa. It's about being together with your family, and sometimes they just can't follow you for a variety of reasons.
Yep, and if there is absolutely no way you can take your family to the place you are from, then struggling through the trials and tribulations of J1 sponsor tansfers, COS and AOS might indeed be the better option.
