When I applied for a US tourist Visa (and eventually got it – for 10 years) I said that I was coming for a month only, but since than my plans had changed and I’ve been here for 4 moths already – for traveling only. Next month I plan on going to Peru and after wards back home, because my I-94 expires on April 11th.
Now the family that wrote me the invitation and were listed as the people whom I was staying with while in the US tried to invite another friend of theirs, who was refused a visa, because of me. Apparently, at the embassy, they asked her if she knew me, and she denied because everybody completely forgot that initially I was listed as staying with them.
Now, my question is, can I call somewhere or write some letter anywhere, explaining that I only staid with them for a week or two and that now I am traveling??? Because I would **** it if they could not invite none of their relatives because of me
