Thanks! We supported it with my job (I'm a doctor), my previous travels (to USA and Mexico recently), we also applied through a lawyer who helped us organize the application and she sent it through her account with a cover letter, my husband's bank account and the purpose of visit was to see us during these difficult time of COVID 19.
It's hard to get a TRV for all coming of a non developed country like mine, we also said we didn't want to jeopardize my spousal application. I wouldn't know what suggest you between applying inland or outland because I haven't researched about the inland conditions as it was not my case. I guess it would be better for you inland but do your research and you have to consider if you have high or low chances to get the TRV too and the time for giving the results of the TRV (4 months in my case)
