Your examples in 3 and 4 are perfect. In number 1, 'information' is a noun-countable noun so doesn't have a plural - other examples are 'rice' 'furniture' 'people'. If something is happening soon, we say it is 'forthcoming' so if you were going to visit a friend say in the next week, you could say 'my forthcoming trip to visit ........' Also, if you travel/visit anywhere you 'go to' - eg 'to the supermarket' - 'to Iran' we would not say ''I am going for the supermarket' - we would use 'to'. We use 'from' and 'to'. I am travelling from China to Iran. On your return journey you can say 'I am travelling from Iran back to China. In number 2, we would not put 'the' in front of the company name and also not use 'company'. If you say 'the Amazon' it would refer to the River Amazon in South America. For the phrase 'try to looking' you can use 'searching'.

Good luck with your visit. Westerners are advised not to visit Iran as it is potentially dangerous but as you are from China you will probably be fine.
