Actually, yes. It can be evidence of presence. Also, depending on the benefit applied for and received and whether or not it was a benefit to a US Citizen or non-citizen, this can raise questions about public charge. Please see an immigration attorney so a professional can analyze your individual situation.
I strongly suggest that you seek the advise and representation of an experienced immigration attorney. The process may just look like submitting simple forms but it is actually much more complicated. If you are not trained in immigration law, you can actually make serious mistakes that have permanent consequences. It is much harder for an attorney to undo your mistakes later. It is better to do it right the first time.
Each country is a separate sovereign. Each sovereign will determine their own rules or laws related to immigration. You must speak with an attorney from the jurisdiction or country you wish to visit or migrate to. A competent immigration attorney licensed in the country you wish to travel to will be able to give you information about whether you would be eligible to receive a grant of permission to travel or immigrate to that jurisdiction.
I agree with my colleagues. B1/B2 Visas are non-immigrant visas and the applicant is asserting that they have intentions to visit the U.S. and NOT to immigrate or adjust status. It contradicts your intentions of immigrating that were asserted in the adjustment of status (I-130/I-485) or any immigrant visa.

When ICE places an immigration detainer (Form I-247) on a non-citizen in state's custody, the local jailer may hold the non-citizen for up to 48 hours beyond time of release from local jail (weekend days not counted) so that ICE can investigate that person or take the non-citizen in to custody. If ICE does not pick him up within those 48 hours then the local jailer must release him from state custody. Local jailer would be committing crime of false imprisonment and is personally and...
I recommend that you discuss your situation with an immigration attorney to be sure. There are too many things that can go wrong in immigration law and it is always best to retain an immigration attorney with experience to get you through the process.
CBP (Customs & Border Protection) can provide non citizens with evidence of I-94 and entry if an I-94 is lost. However, if you were not inspected at the border and never received a visa stamp in passport or I-94, then you may need to speak to an immigration attorney who can analyze whether you had a constructive entry under existing case law.
It really depends on your family's unique situation. If you plan on remaining in the U.K. for several months then you should probably adjust through consular processing. Remember, if you enter the U.S. on a non-immigrant visa you will have to be clear about your intentions. If you enter on a non-immigrant visa and you are married to a USC then the govt. will likely be suspicious of your real intentions. To avoid any problems or uncertainty you should speak with an immigration attorney before...
