No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
I would probably wait. While you're scores are excellent, Chase seems to get spooked mostly when it comes to a 3rd card. If you're not going to have a need for it while out of country, then there's really no reason to chance it. Your AAoA will gain a year, it'll give CFU a chance to age and you'll likely get a higher SL by waiting as well.
I would not apply for a card I wont use for a while. Apply for it when you have the actual need versus some mythical trifecta.
Aside from the small SUB, you really would not benefit from it at this time. If you were using it and able to transfer URs I'd say go for it.
If you cant, wait till you're back.
I agree with @ChargedUp and @Remedios
Don't apply for a card you don't need. No good can come of it.
Alright, thanks for your input.
I'll probably just wait until I come back.
Waiting never hurts but, what caught my eye is the 62K in exposure.... so, knowing how Chase operates you might want to take into consideration how much 62K factors into your income... If you're safely in the 6 figure income bracket it shouldn't be an issue but, if you're not it might be a reallocation from other cards to open a new card in addition to the 2 you have now.
