Hi there! Most of us have done our own processes as DIY. If you have trouble understanding the paperwork and the process, an alternative to an attorney is to use a service like those who are “visa Journey partners” in the website margin. (I haven’t used them, and I’m not endorsing them, just stating that the option exists).
It will take up to two years to get your partner here. US immigration is not fast, cheap or easy.
But you’ve made a good start with finding VJ. Even folks with lawyers come here to ask questions.
