US Immigration from Ecuador

Hey there! I was wondering if somebody can help us with this issue...

I submitted the adjustment of status form with the application for employment authorization a month ago.
I received a receipt for the employment authorization form but nothing about adjustment of status (even though I included the form to receive a text message or email when they start working on the case)
I'm starting to worry, what could I do to get information?

My Fiancee already has a visa interview accepted by the American Embassy

( Consulate) in her Country of Ecuador but the I 134 A is still pending die to nonconfirm notice with USCIS in Texas. Can she be denied at interview ?

Hey there, I have a few questions about this form, I've read the instructions but it's not super clear.

I had a J1 student visa so I had SEVIS number. Now I am in the adjustment of status (K1 visa) process and as a part of the FORM I-765 (ITEM 26) it asks for a SEVIS number. But I am not sure if I should include my last SEVIS number or nothing at all.

Thanks for your help.

Presented because it's interesting and potentially helpful.

Once you hit this credit score, experts say you're 'good' here's how to get there

These days, it's common for lenders, cell phone companies, landlords and even utility providers to check your credit before deciding if they want to do business with you.

The big question, though, is what exactly you must do to impress those companies and make them comfortable taking you on as a customer. Most credit scoring systems run on a scale of 300 to 850, but do you really need a perfect score to get the best rates? [...]

Mother in law tourist visa got denied when renewing it (weird I know) even thought no this has changed and she never stay here longer than what she should have.

Anyways, my question is, she got denied last week, can I reapply now or do I have to wait a certain period of time?

thanks!
