Been busy so let me give an update.
MIL arrived early April on a Tourist Visa from Philippines, She was asked upon entry "Where she was staying, and our address in Texas" (My wife had supplied her our address already) and she was also asked how many luggages she had, She only came with one. She said this was all that was asked.
She has been here about 2 months now and we took a trip to Cancun Mexico last week. She entered immigration line with her daughter, and I watched the entry process they just asked how long we planned to be in Cancun which was a week, Thankfully no line entering immigration due to early flight.
When we got back to USA we entered at DFW airport late and no lines again, we took her thru the USA side of entry and I went to gate and CBP asked her nothing, and asked me how many days we were in Cancun, I suspect since she was with us it was reason no questions.
Other than that it's been a nice visit, it's her first visit to USA, we had 38 degree temps on her arrival and had a party for her, and now yesterday was 95 and had a pool party. She had never experienced cold like that.
Wife and MIL are headed back to Philippines in two weeks, and I will follow a couple days later for a month stay, longest I can stay without paying for visa extension. We have 3 other Fil Am couple flying in from USA and we are gonna island hoping in Sargiuo.
