Got my SSN in November (immigrated with my american wife ) and got an unsecured Discover IT approved for 500. Never piggybanked on her credit report since hers is bascially non existance having lived overseas for long.
Today a day or so after my third statement cut they increased it to 1500. I tried the double dip but they declined that, which is fine.
Other cards are Amex delta gold with a 1k limit and chase freedom with 500.
I mainly used the Disco for the category spend like amazon and gas stations. Not using it heavily for the last month or two basically just filling up the car. Have been using the Chase freedom as my daily driver with amazing casback I get through Apple pay and utility bills.
Maybe total spend all together in three months about 200 or 300 left a small balance to report on there once or twice.
I dont think they like heavy use that much although I have read about it a few times.
Congrats on the auto disco luv!
Yes most will let you know, as they are proud to auto increase, i suppose lol
however, not all of them let you know by sending email.
