I would say that the best advice is to keep at it, and not waste a day's effort. The link to federal government is easy to acquire. But one of the things I have seen is that some people look at doing what has to be done as something of a hobby or pasttime, done when convenient, perhaps not really focusing. The only way to do it is to do it, with focus and time is the key. Go at it hard. Let the others who are casual about it falter, but you must work at it as a professional person does any job. Also I would suggest considering an immigration lawyer, and there are those specialize, such as UK to US. Similar to my comment on the only way to get it done is to do it and not treat it as a hassle but as reality, I say something similar regarding immigration lawyers: since they do charge fees, and I have seen as low as $3,000, and of course they go higher, so taking a perspective that it might cost $5,000 (who knows, look into it) or whatever the cost, the real (emphasized REAL) issue is what is the value of getting it done? If not worth $5,000 then I would say the desire is not worth the effort anyway. If it entails staying up nights, then it is worth it. It is a tough love type of approach: do it, or get off the pot so to speak. And it is true that some immigration lawyers appear to just be an intermediary for the paperwork with the federal government (and some are), so it goes back to the question: why pay for a lawyer? Well, then don't pay for one, but stay on top things down to the minutia and waste not a day or single point in any of it in anyway whatsoever. Even lawyers who appear as simple intermediaries have some value, as they know the system, they monitor the situation, make recommendations, etc. So whichever it be, on your own or with an immigration lawyer, it is a matter of prioritizing and getting done exactly what needs to get done, and getting it in motion today and treating it as a serious task that you will do, and do right, from beginning to end. Not everything is in any our control. But it is what IS in our control that counts, thus doing absolutely all that one can to make it happen is the key, and not moaning or fretting over the whys, hows, and so forth of getting it done, but instead actually getting it done.
